You poor thing! I'm glad you're feeling a bit better now. I get so confused over this whole shunt setting business! You're right, most wouldn't think that going from 30 to 50 would make such a huge difference. I'm only at 3 right now on my new shunt (goes from 0-20) but tonight I feel like I've got really high pressure. I used to overdrain like mad so maybe it's a case of my brain trying to adjust to new pressures...have you ever had that problem? Mind you, to me ALL my pressures feel like they're high, even when I'm overdraining, so what would I know? Very confused tonight. But if it gets any worse, like you, I'm going to my local hospital cos this feels nasty. Hope you continue to feel ok. Just don't go up again!
