<s>[INST] I recently (not 72hrs ago) received a horsefly bite on my ankle - and as of approx 24hrs ago, there is pain in the ankle and now swelling around the ankle. The bite does not appear to be infected (white-ish or raw) but is in the central area of swelling: The bite came while I was in remote woodland country ... any concerns or have I twisted my ankle somehow [/INST] Hello dear, Thank you for your contact to Chat Doctor. I read and understand your concern. I am Chat Doctor answering your concern. It is the allergic reaction occurred because of the horse fly bite. I advise you should take cetirizine tablet and prednisolone tablet for the allergy. Take the tablet for three days under your doctors' guidance. Maintain good hygiene by frequent cleaning and Chat Doctor.  This will prevent infection and helps in healing the wound. Also avoid injury to the wound. Wear cotton undergarments this can help in prevention infection. I will be happy to answer your further concern on bit.ly/ </s>
