That's over 2 weeks away. Please don't spend that time in worry .

I'm glad that you have found a neuro that is good and one that you like. Seems to be very thorough .

For the spinal, you lay on your side with your knees curled up in the fetal position or in some cases you sit on the edge of the bed while leaning forward.
They paint a bunch of anti-septic wash onto the area and put in a local; but you'll barely even feel that. From there on out it is pretty much just remaining still for 10 minutes or so while the spinal fluid is collected.

Afterwards, they'll have you lay on your back and observe you for around a half an hour before they let you get up.
As soon as you can, lay down on your back again and stay laying down for at least a few hours. It is good to remain laying down for the rest of the day or 12+ hours so that the spinal canal has a chance to heal.

Drink a couple of quarts of water in the few hours before the proceedure, because being well hydrated prevents getting a headache. Also drink plenty of fluid afterwards.
Getting some caffeine in the couple of hours before the proceedure also helps to ward off the headache (I take 2 or 3 caffeine tablets called 'Wake ups'.)

If you get a really bad headache, and I mean a headache like you've never had before, go back in for a blood patch. That nasty headache is the result of continued spinal fluid leakage and the blood patch plugs the hole.
It gets rid of the headache straight away.
For the blood patch, they take some blood from your arm and inject it into the spinal tap site. It too is fairly painless...just a little poke.

If you are really nervous about having the spinal, you can ask to see if they will do it under fluoroscopy by a radiologist which pretty much ensures that the needle will be placed with precision.

With love, Erika
