this is the BEST pain scale I have seen so far. I really like the color coding from cool blue to hot red. Descriptions of functionality AMAZING and on target. I am also starting a blog at www.zebrastrong.me.. Please follow and like me on on pinterest and check out my new site. It is not much now but it will be soon with your help. ! This has been saved by hundreds since I posted it. . Can someone chat to me and tell me where it is popping up?
