Dear Linda,
Something I posted back in August:
I haven't seen any reference to it on the site yet,so
I thought I'd give some interesting stuff that my
neurologistss in London have been working on.
It isn't drug based in terms of a cure/palliative but
is more of a primary ("why"?) nature.
I was one of their guinea pigs, and had the delightful
experience of being in first an MRI, then a PET,
scanner for over two-and-a-half hours each time.
First they took a base reading, then induced a headache
(with nitro-glycerine!) waited for forty minutes, then
whacked it with Imigran, taking readings continually.
The pain was unbearable, as lying still is not
normally an option when an attack happens. Two or three
millimetres movement was frowned upon!
Anywy at least they got some results. These show that,
although the mechanism by which the pain is delivered is
similar to that in other headaches, such as migraine,
tha pain itself is triggered in the hypothalamus.
This (I am reliably informed!) is where all sorts of daily
rhythms are based (makes sense) and is not associated
with any other sorts of pain. The link has surprised
all those involved.
The full article is online at:

That would explain the link with daily rhythms.
On the vision front - I did have a burst blood vessel in the back of my eye just over
a year ago in an attack. The doctors said there was no connection,
but I have never been convinced. Could your's be the same? get it checked!
