I've heard the occipital nerve block and botox injections are similar and I wondered if that's true. Or, can you get trigeminal nerve blocks to help alleviate the pain of migraines? I've suffered with migraines for over 50 years and have tried everything, from the east to the west. The intensity seems to be getting better but the daily factor remains. With the severe ones at least 3 times a week. For me they are genetic as my mom and my grandmother had them just as bad as i have now. It seems the preventives don't work very well for me and I can't take triptans because i've had a heart attack and still have heart problems, which leaves out a lot of meds.  Anything you can recommend? I still follow the h/a diet. Thank you.
