Thanks everyone!

I have no idea what mantra is im afraid?. I've never really been into this alternative stuff, but willing to learn if it helps me in the long run!.

All she asked me to do was to lie flat with my knees bent for 10-20 minutes once a day, with some books at the same height as what she had in the session.....

Im sure your right, my muscles are easily upset on my back and im feeling back to normal today (whatever normal is!)
