Thanks guys.
I started waking up with really bad headaches a couple of weeks ago, but was able to knock them down with Tylenol, etc.
Last Tuesday morning, got up to go to work (I do part-time running the office at a local garage to keep busy), sneezed, blacked-out, puked, and pissed myself all before I hit the floor. Woke up about 5 minutes later, couldn't stand up, walk, etc. Thought I'd had a stroke (seriously). Had the worst headache I've ever had. Wife took me to the ER, they doped me and ran all sorts of tests.
Turns out my C2, C4, C5 discs were out of place, but it was a case of left-right-left displacement, so it was actually pinching off my spinal column in 2 different places. Sneezing apparently magnified the problem to the point that it short-circuited things.
They put me in one of those screw-up neck braces and referred me to a local neurologist who in turn looked my at scans and suggested that I try a chiropractor first. So I did, and after 4 visits in 6 days, the headaches are gone.
So....we'll see what happens from here. I have to go back to the neurosurgeon for more scans after the chiropractor finishes this week. I was actually surprised that a surgeon would recommend a chiropractor, and that they're actually working together on fixing this.
