Women who have an overactive bladder often assume they’re incontinent, but experts say that if you also have pain in the pelvic area and pain during sex, you may really have interstitial cystitis (IC). IC is a condition caused when the lining of the bladder becomes inflamed, but because the symptoms of the disease mirror those of urinary tract infections and other conditions it is often misdiagnosed. Experts say that people who think they might have IC should remember the “123” of IC—pain, urgency, and frequency—and should talk to their doctor about treatment options.
