Usually if you have a headache that bad after a lumbar puncture, the doctor will do what's called a blood patch.

Contact your doctor and/or the hospital where you had the LP so that can give you the proper advice.

I did a quick search for you about the lunbar puncture headache, and came up with all these posts. : http://neurotalk.psychcentral.com/se...g_searchinfo=1

Members with Multiple Sclerosis frequently have an LP as part of their diagnosis, so you may find the information that you seek by checking out the MS Forum.

If you need another one in the future remember..... plenty of fluids, and lots of caffeine.

I do hope you get relief soon.
