over the past 2 months, I have gotten progressively worse pain in my right shoulder, right in front. It is most painful on incline pressing and the bottom half of the bench press – overhead presses are fine. I am able to raise my arm w no pain in both adduction and abduction. internal and external rotation with my arm against my side are also fine. the only time I get pain in movement if when my upper arm is raised to shoulder height and I internally rotate my forearm (basically mimicking a flat bench with my arm at 90 degrees.
Obviously, I plan to skip any flat bench or incline bench until the pain goes away. Any thoughts on what might be going on? I have been doing a bunch of reading online, but havent found anything that identifies the combination of adduction and internal rotation and what might be causing. Many thanks in advance.
