What Is The Treatment For Blisters And Itching On The Foot?

hello, I had hip surgery last june, I was off all summer. I was walknig around in my grass, I ended up cutting my foot on a small rock in my tard. did nt realize it until it became infected, I traeted infection with antibiotics topical and band aids. Called suergeon when foot was infected as the hip was month old. I was put on 2000mg of cephlexon. Went to my MD. The bottom of both feet had puss modules. The lance them all. put me on steriod cream. Now It is April and I still get the blisters on the bottom of my feet. Sometimes it is on both sometimes just on one or the other. Sometimes there appears to be none. They itch terribly sometimes. When they burst or i pop them the skin eventually peels away. I just pop one today and put the steriod cream on it. It was not there yesterday. Any ideas? Kirk
