In the last few months I have had two dif antibiotics, first one left me diarrhea, by the time I got under control, I had some vaginal itching that ended up with me on another antibiotic for the severe red itching and swelling from my hips to half way down my thighs. The nurse said I had cellulitis. I saw my interest about 7 days later and he said that was not it. The day before yesterday I was almost totally itch free, then last night it started itching again in vaginal area. Today I used some mono state and it burned like crazy and now the red inching burning and swelling is coming back! What can it be?. I also have internal itching inside my legs from the knees down to my ankles. Please help!
