Well, I thought I was ok, last Sunday in the middle of the day my left arm, half my hand and three fingers went numb, (feels asleep and tingly). I've been hopping all week that it would go away , but it doesn't seem to be getting any better. I usually don't ever go to doctors unless I think I'm going to die, but if it's no better by Monday I guess I'll be making an appointment. It could just be Crossfire withdraws.
