Abstract: Techniques for pain surveying and visualization in a bodily region including a 3-dimensional rendering of a bodily region or an anatomical grid for presentation to a subject suffering from pain for collection of pain intensity and pain location information. A device is provided to the patients for display of the rendering of the bodily region or anatomical grid for collection of pain intensity and location information. A pain analysis module may then create an aggregate pain data set for visual data analyses, user reports, or data export focused on one or multiple region(s), as well as the entire body. The pain data sets may include patient data from a single patient or aggregated data from multiple patients.
