Rash and discoloration. Could this be serious? (Photo)

First of all, sorry for your problems.Any time a patient has a red rash or discoloration, the surgeon needs to distinguish between an allergic reaction or infection.If it were an infection you would be having fever, pain, swelling and drainage. If it is an infection, a culture (cotton swab test) can be taken of any open lesions and drainage. The results will return in a few days and your surgeon can tailor the antibiotics to best treat you.A rash can occur from the antibiotic ointment, constant moistness of the skin or allergic reaction to medication.  An allergic reaction can be treated by stopping the offending substance or medicine. Sometimes a steroid injection or steroid cream can help.It is best to see your surgeon, so he can figure this out for you.Good Luck!
