Pushups do not aggravate it very much. I can dumb bell bench somewhat functionally, although i’m much stronger than this allows me to press. I can shoulder press more than i can bench because of pain. The barbell bench and basically any press with a barbell causes it, starting first in my right, then a couple reps more to the left. It’s like an ice pick point of pain at the bottom of my delt, deep along my humerus. The biceps tendonitis from a previous post sounds very plausible. I don’t barbell bench at all btw, but i would love to do it again someday.
