I have a few blisters on the top of my foot from a scald last weekend. I'm going to be walking for 3 days in the hills and was wondering whats the best way of protecting it? I was planning on a coating of Iodine, a patch of cling film and a thinnish dressing over the top to give some padding. I've been doing this all week but I'm just hobbling round at home and not pushing it. Are there any special dressings that would be better? Maybe something to seal it in for the weekend like a specialist post-op dressing? It's healing up well, with no infection so far, I'd like to keep it that way. Thanks in advance.
