I have intersticial cystitis and was cured in just a few weeks with a very new treatment called ozone installations. Most traditional doctors know nothing about this. I had it done by my integrative medicine doctor and she's only been using ozone to treat this for about a year. It's very new. Anyway, it involves being catheterized and having ozone (a gas) put into the bladder for 20 min. That's it. No pain at all, other than a little discomfort when the catheter is put in place, but that is only for a few seconds. To get full relief, a number of installations will need to be done, depending on how bad it is. Initially, I went about 4 times a week. Then 3, then 2. You taper off. While having these done, I also followed a careful diet given to me by my doctor and drank water with baking soda in it to keep my urine alkaline (1/2 teaspoon 5-6 times a day). Decrease as you begin to feel better. Use Ph strips that you can buy at the drug store to test your urine and try to keep it 7.0-7.5 for best results. Not many doctors do this treatment yet since it's so new. You can read about it on the web and hopefully find an alternative medicine doctor (or integrative medicine) that does it, or knows someone who does. It can be expensiveBest wishes!
