The back pain is normal and you described it well I got the headache and by day 5 was so miserable that I had to go get the blood patch. Best thing you could do is stay down on your back for at least 24-48 hours. You don't want to end up with the blood patch...its not much fun either (but it does give you immediate relief)

In case no one told you...you need caffiene! Lots and lots of it. It will help! I hope you feel better soon.
