Re: Bandaid allergy?
I experienced almost the exact thing last spring. Some people are allergic to the materials in the bandage. For me, I have learned that I have an adhesive allergy--to all brands now.
I got a bad burn on my forearm, inside towards the elbow, last spring. I put a bandage over it to protect it. After having the bandage on less than 24 hours, I had horrible contact dermatitis. The dermatitis rash lasted for weeks and the burn wasn't healing as well as I would have liked. I ended up going to the doctor. She gave me one lotion for the burn and another for the rash. As for protecting the burn on your arm, try using gauze as a cover with the coban wrap to hold it in place. It gets a bit sweaty, but doesn't cause an allergic reaction for me. This only works for me for places that coban can easily be wrapped. Things got worse before they got better, but they eventually healed up.
I still have the burn scar, although it is fading, as well as a bit of scaring from the dermatis.
My advice is to go in to have a doctor take a look at it.
