A week and a half ago i was in gym and a kid ran into me i fell and my back cracked really loud, I went to the nurse and she said i was fine there wa no brusing or red ness on my back at first the pain was in my middle back and my shoulders but it was just minor,nothing I couldn't handle, a few days later my neck started to hurt causing to give me headaches, I took some advil but it never took away the pain so for the next 2 days I iced it on and off,the pain went away for a while but now in the last 3 days my neck has begun to act up to the point where if i turn it it hurts my head and makes me nauses right now the pain is severe to the point where my neck and head ache feel better if I lay my head dow ,Is there anything I can do to fix this
