What causes joint pain all over the body?

Pain in many joints at once points to causes that affect the whole body: a viral infection such as parvovirus B19, inflammatory arthritis such as rheumatoid arthritis, lupus, fibromyalgia, polymyalgia rheumatica in people over 50, or an underactive thyroid. Widespread aching with poor sleep and trouble concentrating fits fibromyalgia, which no blood test confirms.

What deficiency causes joint and muscle pain?

Low vitamin D is the one most often checked: MedlinePlus lists bone pain and muscle weakness or aches among the signs that lead to a vitamin D test. Supplements only help if you are low, which a test shows. An underactive thyroid also causes joint or muscle pain, though it is a hormone shortfall rather than a nutrient one.

What is the number one food that causes joint pain?

There is no single food that causes joint pain for most people. The clearest food link is with gout, where alcohol and foods rich in purines raise the risk of a flare.

When should I worry about joint pain?

See a doctor the same day for a hot, swollen, very painful joint, especially with fever or feeling unwell, because a joint infection can damage the joint if treatment is delayed. See a GP if pain has not improved after 2 weeks of home care, stiffness lasts more than 30 minutes after waking, or pain comes with fever or weight loss of 10 pounds or more. Get emergency care for a joint that is out of place or can't bear weight after an injury.

Can a blood test show arthritis?

For some kinds. Rheumatoid factor, anti-CCP, CRP and ESR help diagnose rheumatoid arthritis, uric acid helps with gout, and ANA helps with lupus. There is no blood test for osteoarthritis; it is diagnosed from symptoms, examination and sometimes X-rays, with blood tests used to rule out other causes.

Can high uric acid cause joint pain without gout?

High uric acid on its own does not cause pain, and many people with high uric acid never develop gout. Gout happens when urate forms needle-shaped crystals in a joint, causing a sudden, hot, swollen, very painful flare. See the gout guide.

What causes joint pain? The common reasons, why it can come

Q: What causes joint pain?

MedlinePlus lists injuries, overuse and strains, osteoarthritis, bursitis, gout or pseudogout, infections and autoimmune diseases as causes of joint pain. Viral infections such as parvovirus B19, fibromyalgia, an underactive thyroid and, rarely, iron overload from hemochromatosis are others.

Q: What causes fatigue and joint pain together?

Several causes bring both. Rheumatoid arthritis lists fatigue among its symptoms, and so do lupus, psoriatic arthritis and fibromyalgia. An underactive thyroid causes tiredness with joint or muscle pain, and hemochromatosis brings tiredness with pain in the knees and hands. A recent viral illness can do the same for weeks. See fatigue for the wider list.

The distinctions

01
Wear-and-tear pain and inflammatory pain behave differently
Osteoarthritis stiffness usually lasts less than 30 minutes after waking and gets worse with use. Inflammatory arthritis such as rheumatoid arthritis brings stiffness that lasts longer than 30 minutes, swelling in matching joints on both sides, and often fatigue. That difference decides whether blood tests are likely to help.
02
A positive antibody test is not a diagnosis
Rheumatoid factor and ANA can be positive in people who are healthy, and normal blood tests do not rule rheumatoid arthritis out. Clinicians read these tests alongside the joints they examine, never on their own.

Joint pain is pain in the places where bones meet, such as the knees, hips, hands and shoulders, and most of it comes from overuse, a strain, an injury or osteoarthritis (wear-and-tear arthritis). ¹³ When pain sits in several joints at once, or comes with morning stiffness, swelling or fatigue, the medical causes move up: a recent viral infection, rheumatoid arthritis, gout, fibromyalgia, an underactive thyroid and, more rarely, lupus or iron overload. ⁷¹⁴¹⁶¹⁷ Blood tests help with the inflammatory and metabolic causes; they do not diagnose osteoarthritis. ⁴

When to get help now

Most joint pain is not an emergency. These signs are.

Call 911 or your local emergency number

A joint that looks out of place or deformed after a fall or injury ²
You can't walk or put any weight on a joint after an injury ²
Numbness or tingling around a joint after an injury ²
Over 50, sudden loss of vision or double vision with a new headache, scalp tenderness or jaw pain when chewing ¹⁵
Chest pain or pressure, including pain that moves from the chest to the shoulder, arm, neck or jaw ²³

See a doctor soon, the same day if you can

One hot, red, swollen, very painful joint, especially with a fever: same day ²¹¹
Joint pain with a high temperature or feeling hot, cold or shivery ²
Weight loss of 10 pounds or more you can't explain ¹
Morning stiffness lasting more than 30 minutes, or pain that wakes you ²
A new rash on the face or body with joint pain and fever ⁹
Pain that has not improved after 2 weeks of home care, or keeps getting worse ²

LifeFrom can't examine you or assess a symptom. If something feels seriously wrong, trust that and get care rather than waiting on a test.

What counts as joint pain, and the difference between wear and inflammation

Joint pain covers aching, stiffness and swelling in a joint, and MedlinePlus notes it “can be caused by many types of injuries or conditions.” ¹ The pain often comes from tissues around the joint, such as tendons and bursae (small fluid sacs), and not the joint itself. The one distinction that changes what happens next is wear versus inflammation. NIAMS describes osteoarthritis stiffness as “usually lasting less than 30 minutes, in the morning or after resting,” and rheumatoid arthritis stiffness as lasting “longer than 30 minutes.” ³⁷ Inflammatory arthritis also tends to be symmetrical, hitting the same joints on both sides, and to bring fatigue. ⁷

Is it wear-and-tear or inflammation?

Wear-and-tear (osteoarthritis)Blood tests mainly rule other things out

Common with age, weight and old injuries

Morning stiffnessUsually under 30 minutes ³

Worse withUse and activity ³

Typical jointsKnees, hips, hands, spine, often one side more

SwellingAfter a lot of use ³

FatigueNot typical

Blood testsNo test confirms it ⁴

Inflammatory (such as rheumatoid arthritis)✓ Blood tests help: RF, anti-CCP, CRP, ESR

Immune system attacks the joint lining

Morning stiffnessLonger than 30 minutes ⁷

Worse withRest, eases as you move ⁷

Typical jointsWrists, hands, feet, matching on both sides ⁷

SwellingWarm, puffy joints

FatigueCommon ⁷

Blood testsHelp, but can be normal ⁸

Patterns, not rules: many people have features of both, and a clinician's examination decides. Based on NIAMS. ³⁴⁷⁸

What can cause it, most likely first

Ranked from most to least likely in adults in general. The order shifts with age, sex and history: injuries lead in younger, active people, osteoarthritis climbs with age and weight, lupus is far more common in women, and polymyalgia rheumatica is almost only seen after 50.

01
Overuse, strains and injuriesEverydaycommon
Overuse, strains, fractures and bursitis (an inflamed fluid sac near a joint) are among the commonest causes MedlinePlus lists. ¹ Pain after a new activity, a fall or a repeated movement, in one area, points here. No blood test checks it; an examination, and sometimes an X-ray or scan, does. Very bad pain after an injury, a joint out of place or being unable to bear weight needs emergency care. ²
02
Osteoarthritis and excess weightMedicalcommon
Osteoarthritis is wear of the cartilage that cushions the joints, with stiffness under 30 minutes and swelling after use; aging, excess weight and an old joint injury raise the risk. ³ NIAMS says “There is no single test for osteoarthritis”: it is diagnosed from symptoms, examination and X-rays, with blood tests used “to rule out other causes for symptoms.” ⁴ Weight loss eases strain on the knees and hips. ⁴
03
A recent viral infectionMedicalcommon
Many viral illnesses cause aching joints, and some cause a short-lived arthritis. With parvovirus B19, joint pain is more common in adults, most common in women, affects both sides, “usually in the hands, feet, and knees,” and usually lasts 1 to 3 weeks but can last months. ¹⁶ No routine blood test in a standard panel checks it; a clinician can order a specific antibody test if it would change anything.
04
GoutMedicalless common
Gout happens when urate “builds up and forms needle-shaped crystals in your joints,” and flares “often start suddenly at night,” many in a big toe, with a swollen, red, warm joint. ⁵ It is more common in men, and alcohol, purine-rich foods and chronic kidney disease raise the risk. ⁵ A sample of fluid from the joint is often used with a blood test to confirm it. ²²
Can be linked with Gout
Uric acid
A high uric acid fits gout in someone with typical flares, but many people with high uric acid never develop gout, so a high result alone is not a diagnosis. ⁵²²
05
Rheumatoid and psoriatic arthritisMedicalless common
Rheumatoid arthritis (RA) is an immune attack on the joint lining, often in the wrists, hands and feet, in a symmetrical pattern, with stiffness over 30 minutes and fatigue. ⁷ Psoriatic arthritis comes with the scaly skin patches of psoriasis, nail changes and sometimes “sausage-like swelling of a whole finger or toe,” usually years after the skin symptoms start. ⁶ NIAMS notes that “some people have rheumatoid arthritis even with normal blood tests.” ⁸
Rheumatoid factor
A positive rheumatoid factor (RF) supports RA, but it can be positive in people without RA and negative in some people with it. ⁸
Anti-CCP
A positive anti-CCP antibody supports RA and can turn positive before symptoms; read together with RF it is “very useful in confirming” the diagnosis. ⁸
CRP
A raised CRP (C-reactive protein) shows inflammation and helps diagnose and track RA; a normal CRP does not rule it out. ⁸ See inflammation markers explained.
ESR
A raised ESR (sedimentation rate) measures inflammation in the body and is used to monitor RA activity and response to treatment; like CRP, a normal result does not rule RA out. ⁸
06
FibromyalgiaMedicalless common
Fibromyalgia brings “Chronic, widespread pain throughout the body or in multiple areas,” with fatigue, trouble sleeping and problems concentrating, sometimes called fibro fog. ¹⁴ More women than men get it, and it usually starts in middle age. ¹⁴ No blood test confirms it; normal inflammation and thyroid tests help rule out look-alikes. See brain fog and can't sleep.
07
Underactive thyroidMedicalless common
MedlinePlus lists “Joint or muscle pain” among the early symptoms of hypothyroidism, alongside fatigue, feeling cold, constipation, weight gain and dry skin. ¹⁷ A simple blood test checks it.
Can be linked with Hypothyroidism
TSH
A high TSH (thyroid stimulating hormone) points to low thyroid hormone, an underactive thyroid. ¹⁸ See how to read your thyroid panel.
08
Polymyalgia rheumaticaMedicalless common
Polymyalgia rheumatica (PMR) causes “Pain and stiffness in the shoulders, neck, upper arms, and hip area,” worst after waking and often lasting an hour or more, and it occurs “almost exclusively in people older than age 50.” ¹⁵ It is linked with giant cell arteritis, an inflamed artery condition in which vision changes need care “right away.” ¹⁵²⁴
ESR
Most people with polymyalgia rheumatica have raised inflammation markers such as ESR and CRP, but MedlinePlus notes that “Lab tests alone can't diagnose PMR”; the result is read alongside the age, the pattern of stiffness and the examination. ²⁴
09
LupusMedicalrare
Lupus is an autoimmune disease that can cause “painful and swollen joints and morning stiffness,” fevers, fatigue and a “butterfly” rash across the nose and cheeks. ⁹ Women get it about nine times more often than men, usually between 15 and 45. ⁹ NIAMS says “no single test diagnoses lupus.” ¹⁰
ANA
A negative ANA (antinuclear antibody) makes lupus very unlikely, since nearly everyone with lupus is positive; a positive ANA alone is not a diagnosis, because “totally healthy people can have a positive ANA.” ¹⁰ See autoimmune antibodies explained.
Anti-dsDNA
A positive anti-double-strand DNA antibody, ordered after a positive ANA, helps clinicians decide whether lupus is the cause. ¹⁰
10
Iron overload (hemochromatosis)Medicalrare
Hereditary hemochromatosis makes the body store too much iron, with “pain in the joints, particularly in the knees and hands,” and tiredness or weakness. ¹² Symptoms usually begin after 40, and women develop them about 10 years later than men. ¹² Here the concern is too much iron, so iron supplements are the wrong direction; a clinician reads the tests. ¹³
Transferrin saturation
A high transferrin saturation (a high ratio of iron to transferrin) may suggest hemochromatosis and leads to repeat and genetic testing. ¹³
Ferritin
A high ferritin is typical in hemochromatosis, though inflammation also raises it, so it is read with transferrin saturation. ¹³

These are things a symptom like this can be linked with, not a diagnosis. Several can sit together, and a clinician who knows your history puts them in order for you.

What causes fatigue and joint pain together?

When aching joints come with tiredness, clinicians think about causes that affect the whole body rather than one joint. NIAMS lists fatigue, “feeling unusually tired or having low energy,” among the symptoms of rheumatoid arthritis, and lupus, psoriatic arthritis and fibromyalgia all include fatigue. ⁶⁷⁹¹⁴ An underactive thyroid brings tiredness, feeling cold and joint or muscle pain, and hemochromatosis brings tiredness with pain in the knees and hands. ¹²¹⁷ A viral illness can leave both behind for weeks. ¹⁶ That is why the first tests for this combination usually include CRP or ESR, TSH, and sometimes ferritin with transferrin saturation. See fatigue for the wider list of causes of tiredness.

Joint pain all over the body

Pain in many joints at once, or everywhere, has a different list from pain in one knee. Parvovirus B19 affects joints on both sides, usually the hands, feet and knees. ¹⁶ Rheumatoid arthritis and lupus affect several joints, often symmetrically, with stiffness and fatigue. ⁷⁹ Fibromyalgia brings widespread pain that is not in the joints themselves, with poor sleep and trouble thinking clearly. ¹⁴ In people over 50, stiffness in both shoulders and hips that is worst in the morning points to polymyalgia rheumatica. ¹⁵ Muscle aches rather than joint pain have their own list; see muscle cramps.

Can low vitamin D cause joint pain?

Low vitamin D can cause bone pain and muscle weakness or aches, which can be hard to tell apart from joint pain, and MedlinePlus lists both among the signs that lead to a vitamin D test. ¹⁹ Vitamin D supplements only make sense for this if you are low, so the test is what tells you whether it is relevant. A 25-hydroxyvitamin D result is reported as deficient, insufficient, sufficient or possibly toxic; see the vitamin D deficiency guide for what the levels mean. ¹⁹

Does a positive blood test mean arthritis?

Not on its own. NIAMS notes that rheumatoid factor can be positive in people without RA, and that some people with RA have normal blood tests. ⁸ ANA is a sensitive test for lupus, but “totally healthy people can have a positive ANA.” ¹⁰ A high uric acid without symptoms is common: MedlinePlus notes that “Many people have high levels of uric acid without having health problems.” ²² These tests answer a question a clinician has already framed from your joints; they are not a screen.

Test	What it looks for	What to know
CRP and ESR	Inflammation anywhere in the body	Measure inflammation; normal does not rule out RA ⁸
Rheumatoid factor and anti-CCP	Rheumatoid arthritis	Read together; anti-CCP can turn positive before symptoms ⁸
Uric acid	Gout	High without flares is common ⁵²²
ANA, then anti-dsDNA	Lupus and related diseases	ANA can be positive in healthy people ¹⁰
TSH	Underactive thyroid	High points to low thyroid hormone ¹⁸
Ferritin and transferrin saturation	Iron overload	High is the concern here ¹³
25-hydroxyvitamin D	Low vitamin D	Bone pain and muscle aches, not joint damage ¹⁹
X-ray	Osteoarthritis, injury	Early damage may not show ⁴

The panel that checks these

If a clinician tests, CRP or ESR and TSH come first for joint pain in several joints, with rheumatoid factor and anti-CCP added when stiffness lasts more than 30 minutes or joints swell, because together they separate inflammatory arthritis from wear and tear. ⁷⁸ Uric acid comes in for sudden flares, ANA for a rash, fever or many joints, and ferritin with transferrin saturation for joint pain with fatigue. None of these needs fasting.

Getting a useful test

Write down which joints hurt, whether the same joints on both sides are affected, and how long morning stiffness lasts in minutes.
Note any rash, psoriasis, eye inflammation, fever, recent illness or travel, and when the pain began. ⁶¹⁶
For a suspected gout flare, a sample of fluid from the joint is often tested alongside a uric acid blood test. ²²
Mention supplements, including high-dose biotin, which can distort some lab tests, and any iron you take.
Ask whether one raised CRP or ESR after a cold is worth repeating, since an infection can raise inflammation markers for a while.
One result is a snapshot; see why trends beat single readings.

What may help

For most joint pain, movement and weight do more than anything in a bottle. None of this replaces checking the red flags above.

Start with the everyday things

Keep moving: NIAMS describes exercise as reducing “joint pain and stiffness” and building strength and flexibility, and advises starting slowly. ⁴
Low-impact options such as walking, cycling, swimming and water exercise are easier on sore joints. ⁴
If you carry extra weight, losing some reduces stress on the knees and hips. ⁴
For a fresh strain, rest the joint and use an ice pack wrapped in a towel for up to 20 minutes every 2 to 3 hours, without stopping movement completely. ²
Avoid smoking, and for gout, limit alcohol and purine-rich foods. ²⁵

Supplements people look at

Ready-made packs

Joints pack

None of these treats arthritis, gout or an autoimmune disease, and if you take prescribed medicine for joint disease, NCCIH advises not changing it without your clinician. ²¹ Supplements support general wellness. They don't treat the causes above, and if a test finds one, treating that comes first. If you take medicines, are pregnant or have a health condition, check with your clinician before starting anything.

Questions to ask your clinician

Does my pattern look more like wear-and-tear or inflammation?
Should we check CRP or ESR, rheumatoid factor and anti-CCP?
Could this be gout, and when is the best time to check uric acid?
Should my thyroid, vitamin D or iron levels be checked?
Would an X-ray or ultrasound help, or a referral to a rheumatologist?
Which signs would mean I should come back sooner?
