Interstitial cystitis. Is not curable.

I had a shoulder surgery about almost 2 years back and since the same day urinary disorder started and I started to pee very often and the urge to pee never goes away and i've tried all medicines since then but nothing worked and all test came normal. I had urodynamic and cystoscopy with hydrodistention about 5 months back and I was diagnosed with interstitial cystitis and taking comfora medicine and tryptomer since then but the symptoms never goes away and I feel very uncomfortable after I finish urinating and then the urge and incontinence starts and stay ther gor about 2 hours and it is really uncomfortable feeling which never goes away. Please help no doctor is able to get my symptoms under control atleast as I already know that Interstitial cystitis is not curable.
