Fluid is normally found in joints such as knees, hips, and elbows. When too much fluid builds up around a joint, it's called joint effusion. It may cause the joint to look swollen.
Many things can cause fluid buildup in a joint. Examples include conditions like osteoarthritis, rheumatoid arthritis, or gout. It may also happen because of an infection or an injury.
Home care may help relieve pain and swelling. In some cases, a doctor may prescribe medicine or drain the fluid from the joint. Sometimes surgery is needed.
You might feel pain when you try to straighten a joint where you have fluid buildup. Your joint may be stiff or swollen.
Your doctor may suggest rest, ice, and raising the joint (elevation) to help with pain and swelling. Your doctor may suggest using nonprescription anti-inflammatory drugs (NSAIDs) or getting a steroid shot. Or you may need surgery to repair damage.
Your doctor will do a physical exam. You may need an X-ray. You may need other imaging tests, like an ultrasound, MRI, or a CT scan. Your doctor may remove some fluid from your joint to learn more. This is called arthrocentesis. It's done by using a needle to drain fluid from your joint.
Home care can help you manage your symptoms. For example, rest the joint. Use a cold pack and prop up the joint when you sit or lie down. Ask your doctor if you can take an over-the-counter pain medicine, such as acetaminophen or naproxen.
