So for the past 3 weeks ive had this terrible rash under my armpits. There’s red blotches all over. They burn and itch so bad. I was treated with an antibiotic and a cream (dr said it was a skin infection). The cream doesn’t seem to be working and now I am having redness in my vagina and it’s burning when I wipe but not when I pee or anything else and doesn’t itch. Could these two things be related or no?
