This study is looking at how well a product called **QUTENZA** works for people with painful diabetic peripheral neuropathy (PDPN). **Diabetic Peripheral Neuropathy** is a nerve problem that happens when diabetes affects the nerves, especially in the feet. **QUTENZA** is a patch used to help reduce nerve pain. The study will collect real-world information to see if using QUTENZA repeatedly helps to reduce pain and the use of other pain medicines. People between the ages of 18 and 80 with a confirmed diagnosis of PDPN can participate. To join, you must not have other pain conditions that confuse the study, and you should not have tried QUTENZA before. **Important things to know about this study:** - **Participation Length:** The study does not specify the exact length, but you must agree not to join other studies during this time. - **Eligibility:** You need a stable medication routine for PDPN for at least 4 weeks before starting. - **Risks:** If you have allergies to capsaicin or certain skin conditions, you cannot participate. To be a part of the study, you must agree to follow the study rules and visit the clinic for assessments.
