I get really bad OB, and can no longer take the medications prescribed, so I've been looking for alternatives. I had a horrible OB this past week and was SO sick, I raided my medicine cabinet for anything that could comfort me. Now I understand the logic of trying to dry out the sores, so I didn't want to reach for something like Vagisil (which does cut the itch, but keeps it around longer), so I tried good old rubbing alcohol and it's been three days and it's starting to scab up already! I usually get a bad OB around the same time I contracted HSV2 over 4 years ago; not sure if anyone else has the same experience. I don't think I would try this if it was internal, but this time my OB was not "inside". I would put the alcohol on a cotton ball and leave it on the sore for a minute or so. If the itching was really bad, I would do repeat a few times. Hope this helps!
