mystery deltoid ailment

I have a friend who has ben suffering from a severe pain in one of his deltoids. He says it runs from the top of the medial head down to where it meets bicep/brachialis. The other day while benching, he said he felt an excrutiating “tearing” sensation in that same area. Now he said it hurts to move his arm. What could this be?

It was a message from his body to see a Sports Medicine doctor As Soon As Possible. Best of Luck.

I get the same thing. I think its common actually. Tell him to look into ART or do a search on this board. I always warm up my rotator cuff when doing chest/shoulders. When he feels that pain tell him to switch to machines for a bit and let it rest.

Sounds like supraspinatus.
See a doc.
