Joint pain

Joint pain is a very common problem with many possible causes. But it's usually a result of injury or arthritis. In older people, joint pain that gets steadily worse is usually a sign of osteoarthritis. See your GP if you have persistent symptoms of osteoarthritis.

Pain in just one joint

The information on this page shouldn't be used to self-diagnose your condition. But it may give you a better idea of what's causing your pain. You should always see your GP for a diagnosis.

Knee pain

The knee joint is probably the most often damaged joint and is particularly vulnerable as it takes the full weight of your body.

Knee pain isn't always a joint problem. Read about the most common causes of knee pain.

Inflammation of the joint lining

If you've injured the joint recently and it suddenly becomes painful again, the thin layer of tissue lining the joints and tendons may be inflamed. It usually doesn't cause any redness or heat.

You should be able to manage injury-related swelling at home with anti-inflammatories, an ice pack and rest.

Gout or pseudogout

If the skin over the joint is hot and red, and the pain comes in repeated attacks, the cause is likely to be either gout or pseudogout.

Both conditions are types of arthritis.

Gout usually affects the joint of the big toe first, before affecting other joints. It's important to correctly diagnose gout, as treatment will prevent future attacks of joint pain and disability.

Pseudogout is a similar condition to gout but usually affects the knee joint first.

See your GP if you think you have either condition.

Damage to the cartilage at the back of the kneecap

Knee pain that feels worse when going up or down stairs could be a sign of a damaged kneecap. This shouldn't cause any redness or heat around the knee.

The cause isn't really understood, but it can be linked to overuse of the knee.

You can treat this problem yourself with anti-inflammatories, an icepack and rest.

Bleeding into the joint space

If you've recently had an injury to the knee joint, such as a torn ligament or knee fracture, it may cause bleeding into the joint spaces.

This is more likely to happen to people on anticoagulants, such as warfarin.

Signs of haemarthrosis are:

  • swelling of the knee
  • warmth
  • stiffness and bruising, which occur soon after the injury

You should go to hospital immediately for treatment if you have a very swollen knee.

Less common causes

Sudden pain in a joint is less commonly caused by:

Rarely, the cause may be:

  • septic arthritis – a serious condition that causes a painful, hot, swollen joint that you won't be able to move (sometimes with fever) – see your GP urgently or go to your nearest emergency department
  • haemophilia – an inherited condition that affects the blood's ability to clot
  • a tropical infection
  • cancer
  • crumbling of the bone (avascular necrosis) – caused by a lack of blood supply
  • repeated dislocation of the joint

Pain in many joints

Rheumatoid arthritis

Rheumatoid arthritis is another type of arthritis that causes pain and swelling in the joints – usually the hands, feet and wrists.

The pain may come and go in the early phases, with long periods between attacks.

It can leave you feeling generally unwell and tired.

Psoriatic arthritis

Psoriatic arthritis affects up to one in five people with psoriasis. This type of arthritis is unpredictable, but flare-ups can usually be managed with treatment.

Like other types of arthritis, it means that one or more of your joints are inflamed and become swollen, stiff, painful and difficult to move.

A viral infection that causes arthritis

Examples of viral infections which can cause pain in the joints and symptoms of a fever include:

  • viral hepatitis – liver inflammation caused by a virus
  • rubella – a viral infection that used to be common in children

A disease of the connective tissue

Widespread joint pain is sometimes a sign of a disease that affects almost all the organs of the body, such as:

  • lupus – where the immune system mistakenly attacks healthy cells, tissue and organs
  • scleroderma – where the immune system attacks connective tissue underneath the skin, causing hard, thickened areas of skin

Less common causes

Widespread joint pain can less commonly be caused by:

  • a rarer type of arthritis – such as ankylosing spondylitis, juvenile arthritis or reactive arthritis
  • Behçet’s syndrome – a rare and poorly understood condition that causes inflammation of the blood vessels
  • Henoch-Schönlein purpura – a rare condition, usually seen in children, that causes blood vessels to become inflamed
  • cancer
  • some medications – ask your pharmacist or GP for advice if you think your medication might be causing joint pain
  • hypertrophic pulmonary osteoarthropathy – a rare disorder that causes clubbing of the fingers, seen in people with lung cancer
  • sarcoidosis – a rare condition that causes small patches of tissue to develop in the organs
