I have cluster headaches a found a product called Sinol. You can look it up on google.

This was a godsend for me. since I found it I never had to take an injection again. I't all natural so can be used up to 10 times a day. Has never taken me more than 10 minutes t stop my headache. I fugured out what ist does is doesn't let he headache get any worse and then it goes away within 20 minutes. I was skeptical but was willing to try anything. It has cayene pepper in it so i stings for a few seconds. If you try it please let me know how it works fo you. It is had to find so I use to order it on the internet. A Grocery store called Wholefoods is suppose to carry it. My daughter found it for 13.99 a botle at Vitacost.com

Good luck
