Hey Malf, can l ask what you have done to be able to keep lifting?
Because even after 8 months of no upper body training, 2 cortisone injections and doing my physio to a T, l can't even do the simple stuff like picking up a kettle or putting my arm through my jumper sleeve without pain running down my shoulder into my arm.
I just deal with it and work around it.
I went to two different orthopedic surgeons, both of whom told me they did not think there was much they could do for me and that surgery might be worse than what they were seeing on the MRI. Since they make their living doing surgery, and I saw two of them, I took them at their word.
I don't do flat bench or barbell incline or decline anymore.
I try to limit my dumb bell weight to 120 or so for chest presses. I know that sort of caps my size probably, but I am old and not going to get any bigger anyway.
I also think I am suffering from a partial pec tear where the pec tendon connects to the arm. Bicep issue. Knees. Groan.
I just find ways to keep stimulating the muscle without making things worse.
I spent a long time ignoring it and pushing through very painful workouts. Oh, it hurts, well, then, I am putting 315 on the incline press, and I am going to grit my teeth through 8 reps. I suffered probably additional partial tears doing that, and the pain would wake me up in the middle of the night. It felt like somebody was sticking a knife in my shoulder into the bone and twisting it.
So finally I said enough is enough and stopped with the heavy barbells. I tried heavy machine work for a while, but an injury in the same place stopped my prep 10 weeks out from a contest.
Every time I have tried to go back and use a barbell (like the time I tried declines on a Smith machine with 225, felt fine, ok, increase, increase, hey 315 still feels light POP! Ow!) I end up regretting it. I miss heavy barbell work, but it is no longer productive for me and far too risky.
So now I just do dumb bell work and cable and pec deck, and I am very careful and controlled in my movements. I managed to compete and win in a local show with only this sort of chest work.
Thankfully my legs have held up with no injuries, but that may be because my legs have always been weak (from a powerlifter/bodybuilder perspective). It may be that decades of lifting with lighter weights has been beneficial in terms of avoiding injuries to the lower body.
The downside is my legs are a noticeable weak point for standing on a bodybuilding stage (but to the normal public I have large, muscular legs, lol! it's funny how perspectives can differ).
So I don't have any secrets for you. If they can fix it and assure you it will be good to go, then do it. If not, then find other ways to work your shoulders, chest, etc.
Many shoulder movements are still very painful for me, but I work through the pain and have very respectable looking shoulders. But inside they look awful, and I have a lot of pain during normal movements like getting milk out of the refrigerator.
