I believe there may be a link to the weather and my programmable shunt valve.
Found other people talking about the very same thing I am:
I would ask my brain doctor about this but.... Oh wait...That's right, I can't find one who will listen to me.
The search for a competent doctor continues...
In the meantime, I'm finding ways to keep my mind off of my shunt discomfort. I am grateful the it's actually working correctly.
