I have what I believe is a rotator cuff injury. Hurts in the gap between shoulder and tricep when:
1) start with arm at side and raise my elbow as hand goes behind butt (kind of like you are going to start to tuck in your pants)
2. do a shoulder raise when hand midway between a front raise and a side raise

- front raise don't feel it, and side raise feels it only if I exaggerate the elbow rotation up. The normal "bend your hand back with elbow out to the side" doesen't hurt either.

Sure, I could find a doc, but they usually find out I lift and say to lay off it for 6 months....

Any help is appreciated.

this isn't gonna help your bulk very much.....

keep it loose by constant stretching (don't stretch it if it hurts, just keep it flexible if you can comfortably).

Nobody can diagnose you - i myself have a bad rotator cuff, and even i have no idea if you're okay to lift or should be getting surgery.

Make sure you eat enough fat, as if you are cutting, a mistake many people make is significantly reducing fats from their diet. This could upset joints further.

Also, if you're unable to do heavy loads because of this, don't forget you can still do a lot of training w/o a working shoulder - leg presses, reverse hypers, core work, etc

^THe man knows what hes talking about.

yes, there should be minimum stretching, though it hurts but we have to otherwise later it will leave an effect.
