Hi Toni,
I too have suffered with interstitial cystitis for about 30 years. My diagnosis did not come til about 5 years ago. Along with this (which is common) I also have vulvodynia. I have had 6 or so rounds of the bladder cocktails which is injected by catheter in the bladder to help with pain and discomfort. I currently take Elmiron 3 times a day and I also take Tramadol when the discomfort gets really bad.
I have been seen by many, many doctors, but the urogynecologist I now see has helped me tremendously. He also recommended the interstim device about a year ago, but I've been helped by the medication to a degree. I have flare-ups that are extremely uncomfortable, then I consider the device, but keep putting the idea off.
He did say he would give me names of women who have had the device put in to hear if they've had success or not. If I were you, I would give the meds time. If you're taking Elmiron, it can take months to start working. And if you haven't tried the bladder irrigation or "cocktail", I would definitely give it a try. I've suffered with this so long, my life doesn't seem right if I'm not dealing with some sort of pressure or pain in that area. Although, I am better then I was.
I hope you feel better before you have to resort to that, but in the meantime, ask your doctor for some referrals of women to talk to. Wish I could have been more help, believe me, I know how you feel.
Take good care of yourself, God has carried me this far. He will you too.
