Shoulder concerns

Hi. I play baseball and pitch for my college. Last season I ran into some shoulder problems. Nobody ever diagnosed it because my trainers felt it wasn’t too severe. I’ve always been suspicious that it was a rotator cuff injury because of the location of the pain. Lately, I’ve been reading up on it and symptoms of a partial tear (occassional cracking noise) is there. Anyhow, I haven’t felt any pain in the last few months during the offseason. I’ve been working out a few times a week and isolating my shoulder area and it feels alright. I’m just conerned cuz it still makes a cracking sound every so often. I would like to begin throwing again but have a little concern that the pain will re-surface. Anyone have experience with this? Or suggestions on what actions I should take? Thanks in advance.
