I had a rash, my doctor said it was scabies, I have been treating it with lice medicine, sulfur soap, tree tea oil, washing my clothes with hot water, vaccum the house innumerous times, I still have the rash. why? they should be dead already. I see new rash on my chest. I am thinking maybe I am overdoing it and causing my skin to have an allergic reaction or I still might have live one. how? I put medicine for almost 15 days already. very frustrating. how do I heal the rash? I tried everything, caladryl too. take benadry to see if avoid allergy reaction.
