Long time ago I injured my shoulder and could not do these either. I would do one of the machines, my gym had quite a lot
of good ones, that didnt hurt. Every once in a while I would try flat bench and it hurt. I thought I would never be able to
barbell bench or incline ever again. Gave up trying. Probably almost 2 years went by and one day I was walking by the
bench and gave it a try. No pain. I started again but increased slowly. I still do barbell flat and incline pretty heavy. My
Shoulders ache a little sometimes but no more injury. Just trying to say, mabey theres hope it will eventually heal if you
give it long enough.
