Interstitial Cystitis (IC) Support Group
Interstitial Cystitis (IC) is a urinary bladder disease of unknown cause characterised by pelvic and intense bladder pain, urinary frequency (as often as every 10 minutes), and pain with urination. It is not unusual for patients to experience nocturia and pain with sexual intercourse. IC is also known as painful bladder syndrome (PBS), particularly outside of the USA.

Bummer that you have to take it, but if it clears things up, might it not be worth it?
