I had no problems getting my LP done. Very routine, no surprises (other than finding out I am allergic to the iodine they used on my back to clean it before the LP).

I went home after lying in the hospital bed for about 3 hours. Nurses said I'd be just fine to go and do whatever I wanted.

All was fine, until the following night. Around 8 pm I felt a headache coming on. By 9 pm I was in a tub of hot water trying to calm down this raging headache (hot water baths actually ease my headaches). By 9:30 I was clothed (don't know how I managed) and in a taxi headed to the hospital. I am surprised I made it to Triage and through their questions still conscious. I was whisked into the back of the ER and put on migraine medication by IV right away. No blood patch either.

I woke up around 6 am, feeling dandy. Walked with the rack with empty IV bags to the nurse station and asked if they could unhook me. Went and got a coffee upstairs in the hospital.

I hope to never again experience a headache that vicious, nor have need of another LP. Sorry to hear you've been going through the headache. Remain horizontal, take it easy, drink lots of fluids. I heard caffeine helps tons, but also Gatorade.
