The researchers found that around two-thirds of migraine sufferers had rhinitis and they experienced around 33 percent greater frequency of headaches compared to those without any allergies.
"We are not sure whether the rhinitis causes the increased frequency of headaches or whether the migraine attacks themselves produce symptoms of rhinitis in these patients. What we can say is if you have these symptoms, you are more likely to have more frequent and disabling headaches", lead researcher Vincent Martin said.
