There seems to be conflicting info on the web about this - I cannot take any NSAID medications before my c-spine nerve block procedure for 5 days.

Would figure that I am 3-1/2 days away from that procedure and I have a splitting headache and terrible neck pain (working on a full blown migraine) - can I take a half of one of my percocet 5/325?

I know they don't want my blood "thinned". I have had surgery and anesthesia lots of times . . .

Is there anything I can take - or do I head for a dark warm space and a bed?
