This study investigates how well people can identify different levels of pain they experience. The aim is to understand pain perception better to potentially enhance pain treatment methods. Pain is an uncomfortable sensation that can vary from mild to severe, and understanding how individuals perceive it can help in managing it effectively.

Participants in this study will undergo procedures to assess their ability to differentiate between various pain levels. This involves experiencing controlled pain stimuli and reporting on their perception of the pain intensity. The findings will contribute to improving pain management strategies.

• Who can participate: Adults who do not have chronic cardiovascular, metabolic, or neurological diseases, serious psychiatric conditions, chronic opioid use, or uncontrolled hypertension may be eligible. Participants must not use narcotics or tobacco products.
• Study details: Participants will be asked to report on their perception of pain intensity during the study. They will experience controlled pain stimuli and provide feedback on the pain levels they perceive.
