About a week and a half ago i slipped and fell down hard wood stairs, my lower back smacked against 3 or 4 of the steps as i went down, Most of the pain has subisded except for one spot in the center of my lower back and I have been having severe headaches since the fall. Also I should mention that when I was a young teenager I broke my L3 vertabrae in three spots. Is it normal for this pain to be lingering like this? Nothing helps, I have tried ice and heat therapy, massage, Advil, and Tylenol.
