I Am Trying To Recover From My Lower Back Going

I am trying to recover from my lower back going out. My right hip shifted/tilted and due to a slip on ice, making my right leg 3" shorter than right. Chiropractor corrected this two days ago, and adjusted again yesterday. My lower back muscles on right side keep having spasms, making me cry out in pain. Do I keep icing it or do I switch to heat? I have been icing since injury.
