Hello. I just removed a lost tampon yesterday had been in there for 6-7 days. I thought that I had BV before finding the tampon so my doctor prescribed me metronidazole gel. Now that I realize that the tampon was the cause of the foul smell, should I still do the metronidazole gel or is it not necessary? I am not having any other symptoms right now, but is there still a concern for infection or TSS?
