Thanks for your comment. The dr did not specifically give me the advice. I am doing the exercise as advised by friends. Perhaps I shall check with my dr.
Thanks
If the doctor gave you the exercise to help your back, then you should continue. If he didn't then you should check back with your doctor and ask about physical therapy or exercises. If the dr said to do those exercises it would be to help you loosen that part of your back up. When the dr gives exercises like that it could very well be to help you in the future to avoid more problems. If you are doing that without his knowledge, yes you could cause more problems, even permanent problems.
