What could cause face tingling, severe lumbar pain, pressure headache, and tooth pressure pain?

I am 21 and just threw my back out I guess. I have been treating it for five days with advil, a heated blanket, and icy hot pads. A day ago the back pain got worse and I started to get a weird tingling feeling in my face and extremities along with pressure pain near my right temple towards my top right wisdom tooth. I plan to see a doctor this weekend since my pain has lasted longer than 72 hrs, but I have no clue what it could be. Do you?
