I had, I believe a horsefly bite in April this year. I attended the hospital and had antibiotics for the infection and swelling and burning - in fact I had to go back twice for the second lot of antibiotics. However, since that time, I have had extreme burning, itching and pain in my left foot and the mark where the bite occurred is still there, a faded brown round patch. I have osteoathritis in my feet and this hasn t helped, but the burning is sometimes intolerable. I attended the surgery yesterday and have been given Erythromicin to combat any infection left in my foot. Are you able to suggest anything else?
