Interstitial cystitis is a chronic bladder condition that causes pain and pressure in the bladder in the absence of a urinary tract infection. There are two subtypes of interstitial cystitis: nonulcerative and ulcerative. Symptoms range from mild to severe. Most people will experience frequent urination, dyspareunia, a constant urge to urinate and pelvic pain.
A study found that 18% of those with interstitial cystitis also had migraine.1
Interstitial cystitis shares many common comorbid conditions with migraine such as irritable bowel syndrome, systemic lupus erythematosus, endometriosis and more.
