i read your question and understand your concern
i would like to ask that
* your age
*when this accident was happened?
* any x-ray Lumbo sacral spine AP & LAT taken at that time
* are you taking any calcium/vit D tablets?
* is there any
numbness in your legs/
* pain radiating to either leg?
sounds must not be coming when you are having normal bones
if there is still spams/sprian of your back muscles take tab. Mydocalm 150 mg tid for at least 5 days, pain killers like Neoflam 50 mg tid for 5 days take calcium and vit d tablets in routine
but before taking calcium vit d check your blood levels of calcium and vit d
one fresh x-ray Lumbo sacral spine AP/LAT
and take milk and yogert in your diet
and consult orthopedic surgeon for all your matter
i hope my answer will satisfy you
good luck & tc
