On the Apple App Store this Miniatlas of Neuropathic Pain is described as a tool to enhance communication between health care providers and patients.

It's got detailed labeled images related to neuropathic pain, with explanations for the illustrations.

You can search and email the images to yourself, or print to any iOS-enabled printer device.

Available for iPhone, iPad and iPod Touch devices.

This app might be more useful for health professionals than you, but for $6.99 you might find some of the images useful to help explain location of your pain to your providers.
