Migraines: Swimming in cold water helps my condition
Eimear Donnelly is 28 and gets around 20 headache days a month because of chronic migraines.
"It's a really complicated condition, and no-one has the answers so you have to go searching yourself,” she tells Radio 1 Newsbeat.
She swims outdoors in cold water which she says helps prevent the migraines and makes her feel better.
