I'm sry i probaly posted this in the wrong area but I'm new and need this question answered. I recently turned 14 and i was just laying on my bed when my back started feeling a little ichy, that itch started to feel like i was being stabbed by needles, sorta like when my foot falls asleep but a lot worse. Then along with the sharp needles feeling it felt liek it was on fire. Finally that dulled to a numb pain. My back had no rash or anything on it, no red or anything. I think this has happened before but never that intense, any idea of what it might be?
