I am having itching around my vaginal for weeks. At first itching was not much. my doctor has diognized a urinary tract infection before that so he gave me some antibiotics but then the itching became more and more disturbing me, The skin under my legs has became a little dark and creased, I want to know if those antibiotics I consumed caused this and if it is really a yest infection and what can I do to cure that

Please it is horrible I can't even concentrate on my work.
