I have been treated for yeast infection after yeast infection the last couple of months and we all know the itching just drives you mad. I noticed last night after itching down there, i felt a pea sized hard knot, and i was wondering if anyone knows what causes these and what i need to do to get rid of it. Sex has really been painful since my hysterectomy last year, so i thought the yeast infections were caused from the hysterectomy and not having the hormones i used to have, please help, do i need to go back to the gynecologists office, or should i just let it pop on its own?
