At 78 I should not have been wielding a heavy leaf-blower with such gusto. An hour later I could hardly walk. Moving was difficult let alone sitting or lying down, and trying to stand again. I knew I had done somethng drastic to my spine.This was Saturday lunchtime. I managed an appointment with Dr Thomson the following Tuesday after researching practitioners in the Gold Coast area. He found and resolved the problem, and after a night's sleep I am back to normal with only the odd minor twinge to remind me to be aware of my limitations. I cannot praise you highly enough James. I have junked the heavy painkillers.
