Hi I Cut My Finger On A Beer Bottle That

Hi i cut my finger on a beer bottle that broke in my hand cutting the finger nearest my thumb on right hand but across the underneath of that finger from say middle part of the finger at the end/last joint in the finger to towards to tip around to the side cut was quite deep went to the hospital and they x-rayed the finger and then glued it and covered it but from the moment till now 6 days later the side of the finger affected and cut around the cut is numb i can feel at the skin surface and full feeling in the rest of the finger including other side of the finger but the effected area apart from surface feeling is numb if i push it really hard and dig in if you know what i mean i feel nothing? is this normal? will it go and get feeling back? and should i go back go hospital as they haven't done something? thanks Stewart
