I have a belly button piercing and I had changed it to another ring. The ring really irritated my belly button and caused it to be red. I took it out and cleaned it and put polysporn on it and put the previous cleaned ring back in. Though I have been cleaning it every day with hydrogen peroxide and polysporn now the inside of my belly button has a lot of white bumps and is red and itches
Hi, You may be having irritant contact dermatitis with secondary bacterial infection. Consult the dermatologist for the perfect diagnosis and proper treatment.  Remove the ring for few months. Antibiotic, antihistamines and steroid may be considered and apply antibiotic cream initially and followed by mild steroid cream. Hope I have answered your query. Let me know if I can assist you further.
