I think my diabetic husband has cellulitis of the toe. It looks like poison ivy. He will be soaking his feet in out chlorinated pool. He already put on polysporin with some positive results. I found a bottle of unused Keflex, that was for droopy eyelid surgery that was not done. Tomorrow, to the doc, for evaluation and treatment. Yes, this article was a help. I printed it up for him. He liked it.
