Allergies and hay fever may increase
the number and severity of migraine headaches, according to a new study.
"We are not sure whether the
[allergies and hay fever] causes the increased frequency of headaches or
whether the migraine attacks themselves produce symptoms of [allergies and hay
fever] in these patients," Martin said in a university news release.
"What we can say is if you have these symptoms, you are more likely to
have more frequent and disabling headaches."
The US National Institute of
Neurological Disorders and Stroke has more about migraine.
