Thanks...I never thought of using the Tens Out in public! I often get frustrated and avoid places because I am afraid I am going to get bumped or for example when I go food shopping alone. I can't lift alot because of my arm but I get looks like I am just lazy. I even had a gil ask me "why not"? when I told her I couldn't lift a case of water. She said "you look fine". Grrrrrrr.
