Migraine Headaches Support Group
Migraine is a neurological disease, of which the most common symptom is an intense and disabling episodic headache. Migraine headaches are usually characterized by severe pain on one or both sides of the head and are often accompanied by photophobia (hypersensitivity to light), phonophobia (hypersensitivity to sound) and nausea.
There are test blocks they can do (short term blocks) that should be done before the very long lasting ones are done. Please try to get those first.
I hope they do work for you and that you find some good relief from them ^.^
I probably wouldn't do it again.
