Interstitial cystitis is a long-term condition that affects your bladder. Some doctors call it "painful bladder syndrome."
You’ll notice cramps in your lower stomach (pelvic) area and in your genitals, along with pain and tenderness. They’ll get worse as your bladder gets full and when it's almost time for your period. You'll feel like you have to pee a lot, and it’ll be urgent. Sex might also hurt.
