Yes it does sometimes mate, i stretch it after every set. As in after the working, then after the drop ect ect. Even on days am not doing chest i stretch it. She showed me what to do.
Remember back nach i never trained chest for a few wks then went very light when i started again. It is like night and day now, tbh i only get pain if i let the bells go really wide. Like level with the chest, apart from that it's ok.
I used to have it really bad even when doing shoulders.
