rotator cuff hurts like f*** despite deca.. :(

hi bros... im on week 3 of test e deca dbol cycle.. and my rotator cuff hurts like hell whenever i train shoulders or chest... will my deca cure this in few weeks time? wh does this happen? is it because i increase my poundage too fast? should i take an kind of painkiller or glucosamine?

thanks for your help

Watch your form when doing shoulder and chest excercises, also stay away from arm wrestling.

I got the same prob bro, I hope it doesnt effect me when I go on. Just stay strict and dont force out reps. Good luck man
