This would directly impact the diagnosis of your pain. If we can address the other parts of the pain we will have a better impact on diagnosing the pain and curing it. Physiology of pain - Nociception • Refers to the system that carries signals of damage and pain to the brain • Nociceptive neurons have cell bodies in the dorsal root ganglia. These ganglia will send signal up to the brain • Can detect mechanical, thermal, and chemical stimuli
