A long time ago, I had a torn rotator cuff, it was like 5 years ago. I am now in my 5th month of lifting again and I have this terrible pain in the same shoulder. I don't think anything is hurt really bad, I still train, but I have been going a little lighter on the load, though. I heard that if you are sore it's still good to work it out, rather than sit around, however I don't want to make it worse. I don't think it's the same injury from a while ago, that should've healed already, right? What should I do?
