Since taking a trip to India in March, I have had chronic cistitis and 3 dozes of antibiotics. I still have a chronic burning, frequent urinating but not the acute cititis. I suspect it s an inflamatory problem, b/c when I take AZA it helps for a few days. It keeps coming back and I m concerned about kidney cancer as my dad s youngest brother died from this. I am 75 yrs. old, a female.
