Our 29 years old son has had migraine headaches since a small child. He has found no medication that gives him relief or can abort his headaches. His right eye will dilate and droop just before a headache. He has a sensitivity to chemicals and or strong smells. Upon smelling a 'trigger' odor an explosion happens in his head and will progress into a horrific migraine. He is light and sound sensitive before a headache. He will throw up during a headache. He does not like to be touched during some headaches. His headaches begin at the top of his spine and radiate upward on the same side his eye is dilated and droopy. He will often have migraine headaches three to four times a week.
