We're all about helping you fit into your skinny jeans, but wearing your pants too tight can cause all kinds of medical problems. Why? Anything that tightly compresses your legs can damage the femoral cutaneous nerve that runs along your thigh, which can lead to numbness and tingling that can be misdiagnosed as diabetes - or even multiple sclerosis. Lisa Stern is a nurse practitioner who specializes in women's health issues. She says that she's seen so many young people with this issue that she created a name for it: "Tight Pants Syndrome." Numbness in the legs isn't the only symptom. Stern says that tight belts and waistbands can upset your stomach, and increase your risk of bladder infections. It can ultimately cause nerve damage in your waist and legs, and create life-threatening blood clots. The fix is simple. Wear looser clothing. If you have tight pants syndrome, don't be surprised if your symptoms persist even after you give yourself some breathing room. Neurologist Dr. Orly Avitzur says that it can take a couple of months for your damaged nerves to return to normal.
