Patients who suffer from migraine are more likely to experience skin sensitivity or pain as a result of simply brushing their hair or wearing jewellery, experts have claimed.
Around one in four women and one in 12 men develop migraine at some stage, with 80 per cent of sufferers experiencing one or more attacks every month.
Now, a study in the journal Neurology has discovered that 68 per cent of patients with chronic migraine (almost daily headaches) also suffer from allodynia, an unpleasant form of painful skin sensitivity.
Study author Dr Marcelo Bigal, a researcher at the Albert Einstein College of Medicine in Bronx, New York, said: "This condition causes discomfort or pain even during everyday activities like touching one's hair or putting on clothes.
"More importantly, this condition may be a risk factor for migraine progression, where individuals have migraines on more days than not. Identifying risk factors for progression is a very important public health priority."
A recent study by the Migraine Action Association found that sufferers who took supplements containing feverfew tended to experience fewer and milder headaches.
