I woke up in the morning on the couch and noticed my right lower leg had a bite on it and a bruise surrounding the bite, my leg was also swollen along with the veins. Its been almost two months now and the bruise and bite is still there and I ve been experiencing constant feelings of something crawling all over me including my hair, shoulders, arms, ears, and legs but nothing is there well at least not on the surface of the skin that I can see. Also I will feel tiny pricks out of the middle of no where, like on my hand, I would be sitting and suddenly I d feel like something bit me on the hand but nothing is there. This has been going on for two months, please help me.
