hi I'm 18 years old and I was taking a zpack for a cough and I got yeast infection after I finished the round the medication. I started using Monistat 7 and after day 3 I started noticing swelling inside my vagina but I ignored it and kept using it and now the swelling wont go down yes I am sexually active but we used protection and I have birth control so I don't think it's an STD. I think I had a allergic reaction to Monistat 7? And I do have very sensitive skin so I think maybe that did it as well but I did call my doctor and I asked her and she said there is no possible way to have an allergic reaction to Monistat 7 to make your vagina swell so I'm kind of confused help please!!! (The swelling didn't start till I started using Monistat)
