distal bicep tear

i had a full distal bicep tendon tear last november while boxing, then went to surgery at the beggining of december and the doctor reattached the tendon to the brachialis muscle. 2 days ago, although, while making an effort, I felt something similar to a re-rupture, altough this time the bicep muscle didn’t bulge to the upper arm like it happened before. yet, it seems to me that it’s slightly bulged. I feel some pain and weakness in flexion, went to do a magnetic ressonance but still don’t know the results. please, i’m in despair and I ask anyone who was into a similar situation to give me some advice, or give me the contact and the name of a specialist in this field. thank you very much. also feel free to contact me through [email protected]
