There are three types of pain.
Nociceptive pain is mediated by cutaneous receptors which detect heat, cold, severe force and chemical insult.
- Medical term that describes pain from physical or potential damage to the body
- Examples: pain felt from sports injuries, dental procedures, or arthritis
Inflammatory pain happens when immune responses activate nociceptors in response to injury. Pain associated with tumors and post-injury swelling are examples of inflammatory pain.
- An increased sensitivity due to an immune inflammatory response
- Examples: pain, redness, or swelling caused by a cut, bump, and any injuries ranging from minor to major
Neuropathic pain is caused by damage to the nervous system itself (e.g. carpal tunnel syndrome, sciatic nerve pain).
- Associated with abnormal sensations or pain from non-painful stimuli
- Examples: phantom limb, neuralgia, diabetic neuropathy, central pain syndrome
