Joint swelling
Swelling of a joint
Joint swelling is the buildup of fluid in the soft tissue surrounding the joint.
Considerations
Joint swelling may occur along with joint pain . The swelling may cause the joint to appear larger or abnormally shaped.
Joint swelling can cause pain or stiffness. After an injury, swelling of the joint may mean you have a broken bone or a tear in the muscle tendon or ligament.
Many different types of arthritis may cause swelling, redness, or warmth around the joint.
An infection in the joint can cause swelling, pain, and fever.

Home Care
For joint swelling after an injury, apply ice packs to reduce pain and swelling. Raise the swollen joint so that it is higher than your heart, if possible. For example, if your ankle is swollen, lay down with pillows comfortably placed under your foot so that your ankle and leg are slightly raised.
If you have arthritis, follow your health care provider's treatment plan.
When to Contact a Medical Professional
Call your provider right away if you have joint pain and swelling with a fever.
Also call your provider if you have:
- Unexplained joint swelling
- Joint swelling after an injury
What to Expect at Your Office Visit
Your provider will examine you. The joint will be closely examined. You will be asked about your joint swelling, such as when it began, how long it has lasted, and whether you have it all the time or only at certain times. You may also be asked what you have tried at home to relieve the swelling.

The structure of a joint - illustration
Joints, particularly hinge joints like the elbow and the knee, are complex structures made up of bone, muscles, synovium, cartilage, and ligaments that are designed to bear weight and move the body through space. The knee consists of the femur (thigh bone) above, and the tibia (shin bone) and fibula below. The kneecap (patella) glides through a shallow groove on the front part of the lower thigh bone. Ligaments and tendons connect the three bones of the knee, which are contained in the joint capsule (synovium) and are cushioned by cartilage.
