My husband has an infection on the side of his foot x's 1 week that has increased in size from the original size of approximately 1" (blisters, redness and red dots around the initial site). Over the course of 5 days the blisters have broken and the infection site has enlarged and now the foot is swelling along with redness spreading away from the site. His foot is quite painful when walking and must use a cane since yesterday to avoid putting full weight on the foot. I've been cleaning the site with peroxide and antibiotic creams and sometimes with Aveno anti-itch cream. We first thought this was poison ivy as we do have this plant around our home, but this looks different and I now believe he may have a staph infection and needs to be on antibiotics. Please give us your opinion
