Yes, I suggest you see a doctor. If you have a biceps tendon tear or a severe muscle tear you may need surgery to fix this. If your symptoms are just minor, they can splint and treat with medications. Muscle/tendon injuries can be very difficult to get over if not appropriatley treated. The least thing they can do is get you on a prescription strenght anit-inflammatory medication. Also, rest the arm as much as possible. Ice the area 20 minutes at a time 4-5 x's a day. This can also help with pain/swelling.
Good luck and speedy recovery!
