I agree that a regular zig zag machine is preferable to the zig zag foot.
Rodney, I'm glad you have such a good attitude. That is so important. And I'm glad you are feeling better. Keep up the good work! However, don't expect too much of your body too soon. Ask me how I know!
Tammi, I'm sorry to hear about your husband. He might want to ask his physical therapist about manual lymph drainage, which is a gentle massage-type procedure that can really cut the swelling down. Again, ask me how I know!
