My husband fell on his back, landing on a block of wood.  He felt a burning/stinging pain in his low back (like hed cut himself) & felt like vomiting.  He has taken a muscle relaxant, put an ice pack on for 15 minutes, had a bath & is icing again.  What else can I do for him?  Should he get an x-ray?
If the pain does not resolve within a week, then an x-ray would be in order. Continued icing is a good idea, as are continued muscle relaxants. But for the first few days rest and pain control are the main objectives.
