Messy and disruptive sneezing annoys everyone. However, Katelyn Thornley from Texas just don't seem to get enough of her mystery disease that makes her sneeze repeatedly.

Sneezing generally ends as the allergy or cold subsides and a person generally sneezes for a 12 to 14 times a day. But for Thornley, sneezing never ends. The Texas girl started sneezing interminably nearly one month ago, sometimes sneezing up to 20 times a minute, making it up to 12,000 sneezes a day.

Initially, 12-year-old thought that it was because of a normal allergy to something, however, her sneezing fits have become serious over the period of time. Thornley's legs have become weak and she complains of a constant pain in her abdomen because of repetitive sneezing.

So far, Thornley has visited 6 doctors. However, they seem to have no clue about what is causing her condition. In addition, they have already ruled out the possibility of a viral allergy.

"Sometimes I wish I could leave my body for a little while so I could watch myself sleep and be at peace because even in my dreams, I sneeze," said Thornley, in an interview with The ABC.

Thornley stops sneezing only when she is asleep. Thornley's parents are hopeful that someday they will be offered an explanation that will clear their doubts about their daughter's mysterious condition.

While sneezing does not kill anyone, health experts recommend people not to stop their sneeze. Alan Wild of the Saint Louis University School of Medicine says that stopping a sneeze by pinching nose or sneezing by closed throat could lead to a few problematic conditions. Some of these conditions include an injury to the diaphragm, blood vessels and ear drum.
