I wouldnt do chest, triceps or back, and only do concentration biceps when your arm is properly supported, actually I wouldnt do anything at all till I knew exactly whats wrong..
You dont know the world of utter shit you could get yourself into if you put tension on, and fully tear, something thats only partly broken.

Seriously, I know a guy at my job who will never, ever, retain more then *at most* 75% mobility and strength in his shoulder, and that is after years of surgery and being home from work.
He spent almost half a year having his wife bathe, clothe and wipe his ass for him after the first surgery (not making this up, he couldnt wipe his bottom himself), and this happened because he went back to work after the dock told him to stay home for 6-10 weeks due to a partial tear.
He made it through a day on painkillers, lift his hand to scratch his head and *POP* His planned life down the shitter in an instant..

His wife was expecting their 2nd child, he was gonna buy a house, now he had to sell his car and move to a smaller apartment to even afford putting food on the table for his family.

Dont risk it, you'll loose perhaps a week of your cycle if you dont work out and it turns out to be nothing serious (whoopda bif effin deal in the long run), but you can loose a friggin whole lot more if you dont have it looked at.
