Hi, last night I slipped walking down the stairs missing the last couple of steps landing sharply on my right lower back. When I landed at the bottom of the stairs, I tried to move I was in so much pain that I started to break out in sweats, I was nauseous, and I felt like I was going to faint. Now everytime I try to stand up I break out in sweats and feel faint. My lower back is very soar and everytime I move my legs I feel a sharp stabbing pain in my back, I become dizzy and start to breakout in sweats. Once I lay down, the sweats stop and I no longer feel dizzy. Can you tell me what is happening and what I should do?
