I feel your pain. Definitely get the blood patch asap.
My bozo doc (10 yrs ago) listened to me complain about my headache for 2 weeks. I couldn't work, a shower was a stuggle. It sure didn't start my life w/MS very well.
My relief took a good nights sleep to be felt. I woke the next day feeling like a million bucks and cursing the @#$% doctor.
Please don't wait.
