Hi Dr.,My right labia minora has become swollen, and not sure if this is normal. I went for a long bike ride and a long run on Saturday. I was on the second day of my period and decided to use a tampon and also a pantyliner. There is no discharge, it just feels irritated. I don t think this is serious, I hope I am right, but want to make sure. I am not sure how long it s been swollen, I just noticed it yesterday. But the area felt irritated after I was done with the workout on Saturday.
