I was reading the postings and came across yours in particular. I have interstitial cystitis a condition of the bladder. I have ulcers in the lining of my bladder and always feels like a bladder infection. It started off very mild just for hours at a time. Anyhow especially after sex. besides looking into I.C make sure you and your partner wash before sex and then also urinate before and after sex and keep clean. I hope this info helps I know how crappy a unrinart tract infection can feel. Get better.
