I get migraines all the time. I've had them since I was a small child. I got all kinds of perscriptions from my doctors and nothing ever worked other than crying myself to sleep. But when I started smoking marijuana I didn't even realize until three months later that I hadn't had a migraine in all that time.

I dont know if it'd be the same for you because my pain used to be chronic. But I find that smoking up is preventative medicine.
