I'm so sorry you're having to go through all of this! It's so difficult to manage when it's one thing after another..I completely understand!
Just out of curiosity, what was your pressure? I assume they've explored the option of low pressure headaches/leaking. Unfortunately, IIH does make us more susceptible to other headaches, so there are many possiblities. You must be so frustrated and disheartened! Have you found
anything that helps to relieve some of the pain? Warm or cold compresses over your eyes or at the base of your skull..heating pad or cold pack on your spine. Does position seem to help..better when you're flat or up? Changing position can help for low and high pressure, but I'm not sure about any of the others. I haven't tried them, but there are members that also have mentioned using 4Head (which you can get on Amazon.com in the states) and the Migracap..I think there's more information in the Alternative Therapies section about that one.
I do think it's very encouraging that your neurosurgeon seems to believe you and is willing to pursue other options..hopefully you'll find relief soon!!!
Take care, and please keep us posted!
