Hyperalgesia: Understanding the Increased Sensitivity to Pain
Hyperalgesia is a condition characterized by an increased sensitivity to pain. It occurs when the body becomes overly responsive to painful stimuli, resulting in a heightened perception of pain. This condition can be caused by various factors, including injury, inflammation, infection, or exposure to certain substances. Hyperalgesia can manifest in different forms, such as thermal hyperalgesia (increased sensitivity to heat or cold) or mechanical hyperalgesia (increased sensitivity to touch or pressure).
The underlying mechanisms of hyperalgesia involve changes in the way pain signals are processed in the nervous system. When tissue damage or injury occurs, immune cells release chemical signals called cytokines and prostaglandins. These chemicals sensitize pain receptors, known as nociceptors, leading to an amplified response to painful stimuli. As a result, even gentle touch or non
