I have lost count on the number of times I have been unable to stand let alone walk.
Over the past 20 years I have spent litterally months flat on my back.
This all stopped a few years back when I went to a physiotherapist who was keen on teaching people how to treat their own back.

I can now avoid back problems but I need to exercise and stretch for 5 mins each morning and night.

If I get lazy and stop the exercises and have problems I now know how to fix it before it gets so bad I'm imobilised.

Works for me.

Regards,
Phill

I know that the voices in my head aint real,
but they have some pretty good ideas.
There is no such thing as a quick fix and I've never had free lunch!
