Well, it has taken longer than the 24 hours they said for the headaches to stop when I was upright for too long, but they have stopped. Annie helped - I went in and laid down on the futon in the computer room and she laid down and snuggled on/with me the almost the whole time.
She's such a sweetie. Still sore in the lower back area, but I understand that's normal.
I will say this - if you ever have to get a spinal tap and they give you the option of doing it with a radiologist - DO IT! The actual procedure was almost nothing. I laid flat on my stomach, he took a couple x-rays and marked my back. The worst part was the numbing stuff, which did burn for a second or two when it was injected. Other than that, all I felt was literally just some pressure when the needle went in. Even the radiologist said that the procedure has gotten a bad rap because of the bad experiences people have when it's done in an office. It may be cheaper in the office, but the ease of the procedure makes it totally worth it IMO.
