A 12-year-old girl in Texas can't seem to stop sneezing -- and doctors have no idea why.
CBS DFW reports Katelyn Thornley started sneezing incessantly about a month ago. The sneezes come about 20 times per minute -- sometimes a dozen times in as many seconds -- adding up to about 12,000 sneezes a day.
"It just started in little spurts. I just started sneezing. I thought it was like, oh, I'm just allergic to something," she said. But now the sneezing fits are taking a serious toll. "I'm constantly in pain with my abdomen, my legs are hurting because I've been weak and I can barely eat."
Since the mysterious malady developed, she's had to stop going to school and can no longer play her clarinet in the school's band.
She's seen six doctors so far, and none of them knows what's causing the problem. They have ruled out allergies or a virus.
