Monistat 1

Last week I went to the doctor and recieved antibiotics for a bacterial infection that I had. I didn't realize that the antibiotics were going to give me a yeast infection because I had never had this happen. A week after finishing my medication I noticed that I had a yeast infection. I was having very iriitable itching and burning. I went to the store and purchased a box of monistat-1. I believe I purchased the wrong kind because I got the Anti-fungal kind. After I used it before I went to bed I noticed severe swelling afterwards. Does this mean I had an allergic reaction. All of my other symptoms are gone. No itching, burning or discharge. Just the swelling. What should I do now?
