Friction: Probably a result of friction along fascial planes between muscle groups and/or tendons. May occur due to some minor swelling/inflammation that could occur with intense training. Be sure to hydrate, eat well, and give your muscles time to recover.

Biceps: Very difficult to repair after 2 years. Usually requires grafting. First step would be a MRI to see what the status of the tendon and muscle are.
