Migraine in my Head

I am 71 years old. I have had migraines since I was 10. They stopped when I was 59 only to start back up this year. I can remember laying in bed with a belt wrapped around my head and me pulling it until I could no longer make it tighter. Someone told me you could not feel two pains at one time. Guess what? They lied. I have Polymyositis and have been on steroids for over 30 years. I found that when I was on high doses of Medrol (the steroid I am on) I did not have migraines. So one of my doctors told me to up my steroids when I felt a migraine coming on. It worked great, but if you know anything about steroids you know that is not a good thing to do. Imitrex injections worked great for me . The neurologist tells me now that at my age they are bad for my heart. So what's a girl to do? My heart goes out to all of you who are just starting your journey with the Migraine Demon. With all my soul I would like to see someone come up with a cure for migraines. Not being able to use Imitrex I opted the other night to up my steroids and that worked great. I wish it was a safe alternative, but I know it is not. Until the neurologist comes up with something for me to try I guess I will just lay in bed and get the belt back out or take my chances and use my stash of Imitrex until I run out. The poor neurologist every time he suggest something I tell him I have tried that in my younger days. I guess I will just start all over again and go through all the standard drugs they put you through. I know I can't use Botox because Polymyositis is a connective tissue disease of the muscles.
