I recently had a lumpectomy and xeroform a was used on the incision site each time the dressing was placed my breasts would become itchy after 5 days I went back in surgery with cellulitis in the affected breast upon leaving the hospital after the second surgery the nurse place the xeroform in areas Beyond incision site and I became very red and itchy. How do I know if this is a reaction or just a hypersensitivity so that my doctor doesn t use it anymore?
