Joint pain is the feeling of discomfort or pain in a joint or joints in the body. Joints are spaces or areas where two or more bones come together, such as the hip, knee, shoulder, elbow, and ankle. Joint pain can happen with or without movement and can be serious enough to limit movement. People can describe joint pain as discomfort, inflammation, increased heat or a burning sensation, pain, stiffness, or pain.

Joints allow our bones to move. They are made up of cartilage, ligaments, tendons, bursa, and the synovial membrane. Any of the structures in a joint can become irritated or inflamed in response to a variety of mild to serious illnesses, disorders, or conditions.

Some causes of joint pain require urgent treatment. For example:

  • If you have an infection in a joint (septic arthritis) then you will need to be seen in hospital as an emergency.
  • If you have a broken bone (fracture) which involves a joint.
  • If you are thought to have rheumatoid arthritis then you will need an urgent appointment with a specialist because starting treatment early will reduce the risk of long-term problems.
