One Best Self reader asked: I have occasional knee pain when I’m active. Should I see a doctor for an evaluation?
Daniel Nicholson, MD of Perimeter Orthopaedics, P.C. says: Knee pain is a very common complaint. The most important symptom to look for is swelling within the knee. An injury to the structures of the knee will lead to fluid accumulation within the joint known as an effusion.
Other important symptoms to look for include mechanical complaints such as popping or clicking, a feeling of instability or a change in range of motion. These symptoms may indicate an injury which could be exacerbated by continued activity and should be evaluated by a physician.
