This diary for chronic pain patients includes a large number of self-report questions to measure the experience of pain, its impact, and treatment.

If you have had a chronic pain problem for a long time, it is probably difficult to remember exactly how you felt and when. This can make it difficult to tell your doctors exactly how you are suffering.

With this app, you can record your pain experience and learn how it changes over time. This can help you to understand what is going on in your body and get better treatments.

This is also helpful for doctors who need to assess the impact of a treatment or a medication. With this, they can make a more informed decision.
