I can't talk or SRS as I've not had it ... yet, but after my 'full works' FFS last year I wasn't so much in pain as intensely uncomfortable which, though it slowly faded, seemed to last a hell of a long time and a year on I still have areas of my face which remain pretty much totally numb. Of course, I don't know how much pain I would have experienced if not for the strong medication (percocet) with which I dosed myself liberally for the first few days. I understand from others that SRS is far less painful than FFS and I sincerely pray that'll be how I'll find it too as I'm a fully paid up, card carrying coward.
