Katelyn Thornley, 12, from Texas has been sneezing around 20 times a minute for the past month and has seen six doctors but no one can figure out the cause.
Medics do not believe the sneezing - which has caused the youngster to miss school - is caused by allergies or a virus.
The sneezing only stops when Katelyn falls asleep—which happens only after she takes Benadryl and listens to the Beatles.

Katelyn has seen six doctors so far, who have ruled out allergies as well as a virus and all are stumped as to what might be causing her sneezing.
Her story is similar to that of Lauren Johnson, a 12-year-old who made headlines in 2010 for her constant and inexplicable sneezing. Lauren also sneezed up to 12,000 times a day and only stopped when she was sleeping.
Four months after her sneezing started, it stopped.
Lauren was diagnosed with pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections, a.k.a. PANDAS, Today.com reports. She was given a treatment called intravenous immunoglobulin, which boosted her immune system and eventually caused the sneezing to stop.
