I am a 46 year old male weighing 80 Kgs. I was fit and fine till about 6 months back. I started having problems with my joints like 1. It started paining in the muscle that joins the left shoulder ball and moves to the bicep. I stopped exercising and the pain went after 2-3 months. 2. I started playing Table Tennis and then started having tennis elbow problem in the right arm. I gave up that after a couple of months and it became fine 3. Now, for last 2-3 weeks have got severe pain in the area just above the back of the right foot ankle. I can walk but have great difficulty in jumping, and ascending or descending stairs. The joint just doesn't take the weight of the body and pains a lot. What is the problem and how can I get well again?
