i woke one morning five days ago and started experiencing some itching sensation on my index and pinky finger tip. the sensation increased until ther seemed to be a sense of bruising and puffy swelling phase happening. it is most noticeable in the morning, especailly upon waking up. throughout the day it settles a bit but is still there. now a looks bruised and swollen in that area. what is it? allergy? nerve upruption?
