No not in 30 yrs

Yes, it comes & goes... I have it mostly controlled by the foods I eat. Until I over do it usually with beer, wine or highly acidic foods then it flare up until it goes away. I was diagnosed in 2007 & tried everything out there. Even learned how to do my own bladder cocktails at home. Finally I said enough is enough. Every time I inserted the catheter it just made it worse. So I quit everything & just omitted all acidic foods and drinks.
