A mother who suffered with "six-week hangovers" due to her migraine attacks had to lock herself in the dark away from her children for days because the pain was so bad.
Kerry Spalding has been suffering with chronic migraines for the last 30 years - since she was just 21 - after first collapsing from a "horrific" pain in her head.
Since her diagnosis, Kerry would have bouts of attacks - sometimes leaving her bedbound for six weeks at a time - and the woman occasionally lose her vision and feel nauseous.
