Classicle Migraine
Very quickly...last Saturday Mail, and article by Rebecca Camber
Sufferers being offered an operation to remove muscles in the head that trigger the attacks.
Firstly, Botox is used to test the result. Then, if there is a reduction in the attacks, they remove the Corrugator muscle.
"Many, but not all, are triggered by interaction of this muscle with nerves in the head."
I feel fairly comfortable about this logic. I'm still convinced that the migraine is caused by a hormone that relaxes something that has gone into spasm, and I have always focused on the blood vessels clamping cos of perceived danger...but there is no reason to suppose a similar process would not be working for other spasms.
