Appropriately named, <u>slow pain </u>oftentimes is not detected until seconds or even minutes after an injury; this is due to the activation of chemically sensitive pain receptors.
Explanation:
According to physiology of pain, slow pain arises when unmyelinated C fibers of the muscles are activated. This is pronounced as a dull and aching pain and is more diffuse in nature rather than fast pain which are more acute and rapid.
Most of the times this pain will not be detected immediately after the stimulus like an injury but may start slowly.
Slow pain can also be burning, throbbing or even nauseous. Chronic pain conditions mostly are characterized by slow pain.
Slow pain is elicited by stimuli like mechanical, chemical or thermal which are received by the chemically sensitive pain receptors on the skin or other organs of the body.
