I have had genital warts for over a year. I have been using Imiquimod cream for about 2 months now. Most or all of the warts have disappeared. Toward the end of the treatment, however, one area of my penis became very red and the middle part of the red area has started to scab (see included picture). It has been this way for about 2 weeks now. Is this redness and scabbing normal with Imiquimod use? Should I be putting some kind of antibiotic cream (neosporin, etc.) on this area? Any advice would be appreciated.
