I was bitten by a dog about 7weeks ago,I really needed stitches but I just cleaned it well and butterflied it. After 10 days, butterflies came off but wound opened after my shower. I put neosporin on it for days, frankincense oil and kept it covered with a bandaid. For the past week I have had a rash around the wound that I thought was from the bandaid so I left it uncovered but it has gotten so much worse. It is tiny itchy blisters that feel like poison ivy. I have been cleaning it with peroxide and putting hydrocortisone on it and some times tea tree oil. Any suggestions how to clear this up?
