Just thought I should add in some advice about the wonderful large exercise balls. I would love to stretch out on one. I see them in use at the gym, mostly by younger members, but my husband gave me a book on Backs that with every photos entry it states: not for those with lower back pain. I have the same experience with neck and shoulder pain and have worked with a Physical Therapist as long as Insurance would allow, and then with a Physical Trainer to over come the pain. Now I work out to run away from pain without using Aleve any more as it affected the condition of my kidneys......a year off Aleve helped to end that problem. It took me three separate periods of needing the help of my Physical Therapist to push me to realize that I must go on with formal exercise to keep my advances in well being. I can add more time in for sewing now. I use TENS too, as needed, before exercise as it interrupts the pain message sent to the brain so that you will not resist the thought of exercise. The problems arise when you need to improve your posture.
