I am experiencing knee pain and knee deformity. the following also describe me: knee swelling, knee weakness, and knee pop. what should i do?

Knee pain: In the absence of a specific injury, knee pain, popping, or deformity may suggest an underlying structural or inflammatory cause. If you have pain in other joints especially the small joints of the hands/feet this may indicate an inflammatory arthritis. I recommend trying an over-the-counter anti-inflammatory for 3-5 days. I also recommend quadriceps strengthening exercises. See PCP if needed.
