Pain excruiating behind one eye?

Starts fast without warning?

Lasts 5 mins - 1 hour?

If yes the you may have cluster headaches as I have - go to www.ouch.com

Also if you have then i have recently found something which has helped me - doctors in the main are not aware of this condition - if it sounds like this is what you have then let me know and I will give you details of my medication which I self prescibe and took me nearly 20 years to find, but note that different things seem to work for different people.
