Any exercise that causes you pain in that area should be avoided. There are plenty of alternatives in the gym that will hit your chest & Delts without having to press. I’ve even found chest machines that allow me to adjust my arc of motion so that I could press. You just have to be creative.
The bicep pain is common. For one it is a common site of what is called “referred pain”. That is, the pain starts & is caused at another area, but the pain commonly spreads to certain areas. Or, the bicep tendon which is likely the long head, is pretty fragile as well & also gets impinged in similar exercises.
I would guess that you can curl painlessly when your arm is supported on a bench or machine, that’s because the RC doesn’t have to fight the traction effect unsupported curling has on the shoulder joint. It also happens with labrum tears, but your mri is clear.
There are a ton of ways to strengthen your RC, just google them or go on YouTube, this is an incredibly common issue. Check some out & run them by your PT.
The truly fantastic thing here though is that your mri is negative. You really have no idea how big of a blessing that is.
Be patient with the RC strengthening, be creative with your choice if exercises in the gym. Avoid pain. BTW, curious, how old are you and for how long have you been lifting? And, do you do other sports?
