So a local medical supply store is loaning me a chair to try. I will start this week. The person I lease from who is in the same building offered to let me try his "ball chair." You may have seen them. You have to balance, so you strengthen your abdominal muscles."
So, I went in to his office this afternoon to try it and was disappointed to find out it had been converted to a doggy lumbar chair. Complete with his water and food bowl and wine closet. They always have dogs in their office. Drives me nuts. Just roam around, eating our food or making kids happy or scared.
