A member asked:

My knee is swollen, stiff and painful what's wrong?

A doctor has provided 1 answer

Water on knee: Sounds like you have fluid in your knee. It can be from an infection, injury, or arthritis. It should be evaluated asap by your doctor, an orthopedic surgeon, or go to the er. Bloodwork, xrays, and possibly an aspiration may be needed. You also have to worry about lyme disease which can be detected by a blood test.
