Joint swelling is the buildup of fluid in the soft tissue surrounding the joint.
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.
Joint swelling may be caused many different things, including:
- Ankylosing spondylitis
- Psoriatic arthritis
- Reactive arthritis
- Rheumatoid arthritis
- Septic arthritis
- Systemic lupus erythematosus
If the joint swelling occurs 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 underneath your foot so that your ankle and leg is slightly raised.
For those with arthritis, your doctor’s treatment plan should be followed carefully.
