interstitial cystitis
"For 4 years I was in and out of doctors offices explaining to them that I was having severe bladder pain (the kind that makes you nauseous, sweaty and feverish). Finally I went to this one doctor and told her I had symptoms of urinary tract infections 12 times in less than 6 months. I had tried changing my diet and nothing had helped. She put me on Elmiron 3, 100mg pills 3 times a day and within 2 weeks I could finally pee. It has been amazing, although I do suffer from frequent headaches (even when we have lowered the dose as low as 3 pills a week), and exhaustion (I had this before the Elmiron but it has been increased while on it). I still recommend trying it, it is better than nothing."
