When The Nervous System Is Damaged Or Does Not Function Properly, It Can Cause Neuropathic Pain

 

Neuropathic Pain

Neuropathic Pain is a type of chronic pain that occurs due to damage or dysfunction of the nervous system. Unlike nociceptive pain, which results from the activation of sensory receptors in response to tissue injury or inflammation, neuropathic pain is caused by abnormal processing of sensory signals by damaged nerves or the spinal cord and brain.

Neuropathic pain is a common and disabling condition that affects up to 10% of the general population and up to 40% of patients with chronic pain. It can occur as a result of various underlying conditions, including diabetes, shingles, nerve injuries, spinal cord injuries, multiple sclerosis, and cancer.

Neuropathic Pain is characterized by a range of symptoms, including burning, shooting, stabbing, or electric shock-like sensations, tingling or numbness, and hypersensitivity to touch or cold. These symptoms can occur spontaneously or in response to certain stimuli, such as movement, pressure, or temperature changes.

The mechanisms underlying neuropathic pain are complex and not yet fully understood. However, it is believed that nerve damage or dysfunction can lead to a range of abnormal physiological and molecular changes in the nervous system that contribute to the development and maintenance of neuropathic pain.

One of the key mechanisms involved in neuropathic pain is sensitization of nociceptive pathways in the spinal cord and brain. This can occur as a result of increased excitability of nerve cells, altered synaptic transmission, or changes in the expression or function of ion channels, receptors, or neurotransmitters involved in pain processing.

Another important mechanism involved in Neuropathic Pain is the activation of glial cells, which are non-neuronal cells in the nervous system that play a key role in immune response and inflammation. In response to nerve injury or dysfunction, glial cells can become activated and release a range of pro-inflammatory and pro-nociceptive molecules, such as cytokines, chemokines, and prostaglandins, which can contribute to the development and maintenance of neuropathic pain.

Treatment of neuropathic pain is challenging and often involves a multimodal approach that targets different mechanisms involved in pain processing. Some of the commonly used treatments for Neuropathic Pain include medications, such as antidepressants, anticonvulsants, opioids, and topical agents, as well as non-pharmacological interventions, such as physical therapy, cognitive-behavioral therapy, and neuromodulation techniques.

Psoriatic Arthritis can result in joint discomfort, edoema, and stiffness. It affects those who already have psoriasis, a skin ailment. This results in red, elevated regions of skin with white and silvery flakes.

Antidepressants, such as tricyclic antidepressants and selective serotonin and norepinephrine reuptake inhibitors (SSNRIs), are commonly used for the treatment of neuropathic pain due to their ability to modulate pain processing pathways in the brain and spinal cord. These medications can also improve mood and sleep, which can have a positive impact on pain perception and quality of life.
