|Alex Doran and his mother|
A 14-year-old boy who thought he had a headache was actually having a stoke.
Alex Doran from Salisbury in Wiltshire collapsed at home while getting dressed for school.
He felt a sharp pain his head, his eyes were rolling and he began vomiting.
Baffled hospital doctors first diagnosed him with a migraine but an MRI scan showed he had a narrow artery in his neck which caused a stroke.
They believe club swimmer Alex only survived because he was physically fit.
