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.

I just joined this group. I get it about the "foundering." Feel like I'm floundering, too.
Been doing some research and from what I can see, and I stand to be corrected, this has to do with MCP-1 in the bladder, which might respond to antihistamines such as Rx Hydroxyzine. CCR2 is involved in the process of mast cell degranulation in bladder tissues. These changes may contribute to the development of symptoms of IC/BPS.
This is very new to me. I don't actually have a diagnosis yet, but all signs point towards it.
