Itching between my butt cheeks seems to not go away. I have been to the doctor twice now to get it checked out. At first the doctor prescribe me some Fluconazole Tablets and Nystatin because she thought I had a yeast infection. After a month had gone by i have not seen an improvement. I went to the doctor again and saw another doctor. He prescribe to me clindamycin phosphate lotion. This also did not improve my symptom. Can someone tell me what's wrong with me.
