Neuropathic pain is caused by injured nerves and can occur suddenly or repeatedly. The neurological signals behind neuropathic pain are distinct from those sent along healthy nerves by injured tissue (which can manifest as pain after a fall, a cut, or a burn). This kind of pain usually results from spinal cord injuries, amputated limbs (phantom pains), and postherpetic disorders, requiring specialized medications known as opioids.
For neuropathic conditions, opioid medications like Tramadol and morphine are frequently helpful. The medications mentioned above are equally effective at treating nociceptive pains, which are the body's normal reactions to painful injuries. This category includes cases of musculoskeletal and visceral discomfort.
