Sorry to hear of your recent diagnosis.
I just had a lumbar puncture done in January. The procedure was done in the Radiology department at my local hospital using a fluoroscopy-guided technique. They tilted the head of the bed up during the procedure to increase the flow of spinal fluid. They use lanicane to numb you up first and there was really no pain just a little pressure. Some people do experience headaches after the procedure.
I'm wierd, I had pain in my forearms, back and neck for a number of days following the procedure. I was able to totally eliminate the discomfort by laying down flat. I also had some wierd hearing problems that corrected once the fluid and pressure in my spine returned to normal.
My results showed positive for ms, however i have no lesions on my brain or spine mri's to confirm the diagnosis.
Hope that things work out well for you.
Peace and Healing
