I have nonstop itching, burning, biting in vaginal area. Initially treated for yeast infection, then 3 was later the itching started again, more intense. No yeast was found but given Difucan again. Last visit to urgent care, given Bactrim for bacteria in urine. Still extreme itching and burning. It's beginning to affect me at work. I'll be going to another dr tomorrow but afraid the problem won't be solved. I'm not sexually active and 49 yrs old. Help,
