urinary tract infection
"I have suffered from recurrent urinary tract infections since I became sexually active. I would get an infection every time I had sex with my boyfriend. I tried countless courses of antibiotics which apparently cleared the infection but when I had sex again i got another one. finally my doctor put me on nitrofurantoin and this cleared the infection immediately. I have still to finish the course. I haven't had sex while taking the last few courses to make sure the infection has cleared fully! "
