I recently had thrush, on the instructions of my doctor I bathed the area twice a day with baking soda, the original infection is gone but over the last two or three days, I've found red lumps between my external labia and my leg, I assumed they were the result of shaving and ignored them, they've now multiplied and some have crusted over, a little awkward and worrying since I'm not sexually active but I was planning on having sex with my long distance boyfriend when he comes here in two days. 

Any clues on what it could be and what I should do?
