According to a recent study in Neurology, migraine may double the risk of Bell’s palsy, a nervous system condition that causes facial paralysis. Researchers in Taiwan have found an association between the two disorders, which previously had not been linked. In the study of nearly 137,000 people, migraine sufferers were more than twice as likely as those without migraine to develop Bell’s palsy.

Giant Cell Arteritis (previously known as Temporal Arteritis) is a vascular disease characterized by inflammation of blood vessels. It can cause a very severe headache that usually strikes people over age 55. The pain is in the temple, and vessels in that area can be tender. In some cases, patients may have other bodily symptoms such as fever, loss of appetite or joint and muscle pain. This is sometimes called Polymyalgia Rheumatica.
