I have about a dozen bug bites on my right labia majora. I've had these bites in the past but never in this area. I believe it's some kind of mite. They started out as a small red spot but quickly changed to a larger size, turning darker. Three of the bites are right on the edge and have intense burning. I wash after each time I urinate. Once the area is clean I've applied an antibiotic ointment and also used ice packs for some relief. I'm already on Bactrin and Cipro for a foot injury so don't think they are infected. I'm at a loss as to why the ointment isn't healing them. For two days I used a cortisone cream with no relief. Please tell me what else I can do to treat these bites.
