I went through a long rough strech of having bad headache/migraines everyday. I was put on alot of acute medications, which none worked, also alot of preventative meds, which also didnt work. Now that i have been put on a BB they have improved alot, i still always have a small mild headache, but not nearly as bad as it used to be. Also i will get bad ones about 4 times a week but they usually only last about an hour or a little more. Another thing is that when i have a bad migraine i will increase salt and fluids and once i get my blood volume up it starts to help me feel better aswell. I dont have alot of advice for you, but i know how you are feeling. Are you on any BB, or is your BP more of the issue, not HR? Hope you start to feel better soon! ~Mary~
