14 yea old son 5’11" 200 lbs. starting having severe bicep pain in march. Its in middle of the bicep in the muscle not the bone. He says it feels like his muscle is tearing apart. His bicep hurts when he throws or tries to do curls or anything using bicep muscle. Shut him down for a month. started throwing again and had the pain come back. shut him down for a month again. started throwing and the pain was still there. Took him to the MISSISSIPPI SPORTS MEDICINE – and Orthopaedic Center. They did an x-ray of his arm. Everything looked good. They gave him some exercises to do with the rubber bands for a month. At first he really hurt when doing the bands, but it got better but still hurt. After the month was up, we went back and they did an MRI. Everything looked good. We waited another month and started throwing again. Still severe pain. He wants to play with it but I want to get it fixed. Any ideas on what it could be? We are supposed to go back to the Dr. soon and wanted to see if you could give me questions to ask. This picture is from last year but he still does this. I was wondering if his forearm laying flat back could be the cause of the problem.
Edited to add: bicep doesn’t hurt when I squeeze or poke it.
