The curse of the parquet floor has struck again.

Despite being only halfway over, the seventh season of Dancing with the Stars has already seen more than its share of medical emergencies. So far this fall, we’ve seen Jeffrey Ross with an eye patch, Susan Lucci with an ankle wrap and Misty May-Treanor with a seat on the sidelines. Now one of the show’s professionals is going to be added to the injury list.

One week after being checked out for stomach issues, we’re learning the real reason behind Julianne Hough’s trip to the hospital. Although her evaluation was initially downplayed, it turns out the country singer - who was discovered to have endometriosis -  will actually need to have her appendix removed.

Fortunately, the 20-year-old has a common medical condition that is found in 5-10% of women of reproductive age. Those diagnosed with endometriosis experience a development of uterine-lining tissue outside the uterus on the surfaces of organs in the pelvis or abdomen where they are not supposed to grow.
