Back pain is an epidemic in our Western modern society.
Look how cats move, and you already may feel “some better”…
This is not the place to write about all the possibilities of treatment [even if I would know just part ot them.

I will mention just “one kind of back pain: back pain which is worsened by stooping for a long time [meaning of stooping: bending forward and downward]
This may happen with comstipation for example.
In this case buy homeopathic globules of Nat.mur D6 and suck for a few days 2times per day 2 globules.
