I know quite a few people on this forum have Interstitial Cystitis and I was wondering must you always have frequent urination to have this? I've had some different/intense pelvic pain for about 1 1/2 years now and I read about IC early on and thought that wasn't it, now I'm not so sure. I know I definitely don't want it! I've been diagnosed with endometriosis, a recent pelvic CT scan showed a fibroid or two. The report was somewhat vague and my GP just says everything is fine. Yeah, fine! I have fibro and vulvar vestibulitis, so IC fits right in there too or generalized vulvodynia. The pain is low in the pelvis and radiates to my back and rectal/vaginal areas. It aches/burns mostly with occasional stabbing and pressure feeling in the bladder area. I took a T3 and it doesn't do anything to relieve the pain, neither did percocet except make me tired or nauseated. The pain often seems to bring on a headache or a migraine. It is driving me insane!!!!! It's flared up the last couple days and interestingly enough I drank Poweraid both days. I've read that artificial sweetners can aggravate IC. I also read that B vitamins can aggravate IC (which I've been increasing) - what do you do if you are low in B vitamins and have IC? There is pain and frequency when I urinate during these painful episodes but not when it's not flared up. Would that alone rule out IC?
