I have be doing Physical Therapy for the last couple of weeks to gain strength in my legs and to help with the pains in my back, neck and shoulders. They introduced me to this wonderful tool to use when I have muscle pain. It is wonderful. I can't describe it to you adequately; but here is the name and It can be found on Amazon. It has changed how I am able to sew.
