Hey all. Got something thats been bothering me lately.

Starting dumbell shoulder pressing a bit heavier than what I'm used to (55lbs) for 10 reps and for the first 3 reps my bicep is under constant stress, like it literally aches alot but once I get the motion going the pain slowly subdues and when I drop the weight the pain fires back up.

Even lowering the weight does this and this pain ONLY comes from shoulder press.... Tried using barbell and it's a bit easier but should this pain be concerning me?
