32 y/o female, I have interstitial cystitis with pelvic floor dysfunction. I am scheduled for a cystoscopy with hydrodistention in January. The last couple days, I've had increased pain with spasms in my bladder. This afternoon, sudden onset right side mid back pain "spasm" feeling that is unrelieved with heat, massage, flexeril and stretching. Severe enough to have me in the fetal position. Doesn't feel muscoskeletal. How do I know if I should seek emergency room care?
