A fit and healthy Scots teenager who suffers from four migraines a day says his life is "at a standstill" due to headaches caused by an egg-sized mass growing inside his skull.
Jack Dow from Aberdeen, began noticing the splitting pains when he was just 15, but the matter started to become unbearable last year. The now 18-year-old, who has been active his whole life and dreams of becoming a Royal Marine, was eventually bedridden with each migraine becoming more intense.
After numerous GP appointments, a CT scan ruled Jack had a 6cm growth of abnormal blood vessels forming inside his head, which was later identified as arteriovenous malformation (AVM) - a development of irregular connections between arteries and veins, which disrupts normal blood flow and oxygen circulation.
