Three weeks ago I went to the urgent care b/c my toe was infected from a pedicure.  Doctor put me on Bactrum (spelling?); took all of the antibiotic; did warm soaks, etc.  Now the toe next to it is tender to the touch and has a perfect circle of blood in the center of it; toe is hard too.
Dear patient you had developed infection because the pedicurist didn't follow the right hygiene practice. May be Bactrim was not that effective for your infection. I advice you to get a complete blood picture and a grabs test just to rule out diabetes because it's known to lower immunity and give infections. Consult again to the physician with test reports, and he will prescribe you another antibiotics accordingly. Till then apply topical t-b act ointment on it regularly for two weeks. Hope I have answered the question
