Sleep on concrete floor or (carpet

) so your whole back is straight!
In India they sleep on pins and streets they never have any back ache I've heard.
Forget drugs as it will do more
bad than good, as you don't know what else you could add damage on you're back.
My treatments is light stretching so you can exercise the muscles as they will be tight with the constant winching of pain.
EDIT lower back pain doesn't not mean the issues are lower back shoulders can cause this the nerves are connected causing pain else where!
