Welcome to NeuroTalk. I am so sorry to hear of your migraines. I have a TBI friend who suffers TBI migraines and fully understand what you are going through.

Have you tried a combination of Tylenol (acetaminophen or paracetamol) and aspirin? Combined they give very good pain relief. You can take maximum doses of both at the same time. The Tylenol should not be taken at maximum dose for more than a week without a few days to allow your liver to clear. The suggested maximum dose is 4000 mgs per day. Aspirin can be taken in an enteric form to reduce stomach upset.

I routinely use this combination for my more severe head aches.

You should also get your blood pressure checked during thees migraines. They may be blood pressure related. A blood pressure lowering med may help. Propanolol ought to be available at most major pharmacies for minimum cost. Walgreens and Walmart have good no-insurance discount plans.

Stay away from caffeine and MSG (MonoSodiumGlutamate)

My best to you.
