I have had clusters just about every other year for 30 years. New headache specialist suggested a 3 doses of Emgality. I'm a little hesitant but not sure what else to do next time they hit. Mine are more cervicogenic, so they said, but I rock back and forth, bang my head and scream. The headaches no longer stop on their own (tried fighting for 2 hours) and they hit a couple of times a day. To stop them, I have to use the sumatriptan injections. However, I give myself half doses of 6mg vials (not auto injectors). I have the kind that has two vials and they clip into a blue container. I hook the injector onto a vial and spin to pop the dose up, and then spin it backwards so I can pull it the rest of the way out with my hand. I put the needle in my arm and use a q-tip to push the black stopper down halfway. The next round I use the same needle (only 3mg left) and push that into my arm with the actual injector. That gets me 4 shots out of the two vials. Can't use too many per day because they will rebound. To stop a cycle I have to get facet injections into my C2-3. Something triggers my muscle and it pinches the nerves. The spasm will only stop with a steroid injection. Not sure why these headaches exist but they are truly hell on earth. I also belong to the cluster headache website but not sure how to go about getting mushrooms. I heard years ago that it works but never looked into it. You would think with technology and medications today, we would be able to put an end to this hell.
