So many varying causes of back problems, it really is a case of what works for you.
A customer in her late 60's, that I go to at least once a year, developed a bad back. A year later she could hardly move around the house and had to sit in a certain position to get any relief from the pain. She was under the care of a private consultant etc etc, and was told it would progressively get worse.
The following year, I expected her to be bed ridden or similar, so was surprised when she answered the door looking 10 years younger.
I asked how she was and she replied that she was fine, and had no back problems. It turned out that six months earlier during the summer, she had been lying on the carpet looking out at her garden and saw that some flowers required 'dead heading'.
She took a chance and managed to get out onto the lawn and lay on a small piece of carpet, reaching to snip the flowers. She did all along the back garden.
The following morning she was surprised that she no pain getting out of bed and could dress herself without trouble. In short her back problems had gone. Obviously due stretching whilst seeing to her flowers. Her consultant couldn't believe it.
She has continued with a stretching regime and has suffered no further problems to date.
