While there are over the counter, aspirinless pills that do work on migraines and stress headaches, those who have severe migraine,cluster,or stress headaches are prescribed more potent meds.
What is surprising, if true, is that at her age and after having five children, she still gets such overpowering headaches.
And before anyone tries to go after me for the above factual statement, men who suffer from migraine or cluster ( which are even worse than migraines ) headaches also get some relief ( not as many and/or a lessening of pain levels ) as the reach a certain age.
