See if you can locate dressings made with a Gortex material...it worked wonders with a burn my son had on his wrist. Here is a link so you might get an idea of what I am talking about

I am sorry you are going thru this still...it is so hard! I would encourage you to talk to your doctor and see if there are other things you can be doing to help the wound. I would encourage you also to email "ask the expert" dr. Serena. He is an expert with wound healing.
