I completely understand what you are going through!
I had my second LP on Monday (first one a year ago without incident), had severe spinal headache for 4 days and I too had to have a blood patch just yesterday. Ugh - now that was a traumatic procedure compared to the LP! Thank God my headache is gone, but now my back is KILLING me today - I feel like I threw my lower back out. It's good to hear that the pain goes away though. This is definitely no fun! Advil has become my very good friend this week.
