Shin wound

Help please. I have a shin wound. It is a month old. It has healed a lot but it seems to have gone a bit backwards. We were using a qtip and applying MMS water. Initially I think it made all the difference in the world but then it seemed to be too strong?? It got these little bumps and got a finger wide red ring around the perimeter of the wound. I make a poultice of bentonite clay, honey, sugar and prid salve and apply it to draw out the infection. It seems to be healing but how should I be using the MMS water or should I be using the CDS water?? Help, Thanks.

The photos are taken from oldest to newest and the white spot is where I had an itching fit and scratched the skin off...ughhh.
