Pain in an arm or a hand

[Mry]

Hello! At me a pain of a ulnar joint (but the most interesting hurts there where usually take a blood from a vein). Pains appear and is simple and at a flexion if the pain has appeared does not pass or take place day 2 3, and to this all dobavljaesja an edema of an arm or a hand of all up to ends of fingers. At pekrashchenii the edema gradually passes or takes place pains. All this lasts somewhere 3 months, but each time a pain more strongly and has swelled it is more. What is it such?.. And how with it or this to struggle?
