Migraine is a type of vascular headache. It is due to the enlargement of the vasodilatation and releasing of the chemicals from the nerve fibers that are coiled around the blood vessels. When migraine attack is there, the temporal artery gets enlarged. The temporal artery is located on the outskirt of the skull, just below the skin of one’s temple. The enlargement of the temporal artery leads to the stretching of the nerves to release the chemicals. The inflammation results in pain and causes further enlargement of the artery, thus increasing the pain.
