Neuropathic pain
Neuropathic Pain
Neuropathic pain is a complex, chronic pain state that is usually accompanied by tissue injury. With neuropathic pain, the nerve fibers themselves might be damaged, dysfunctional, or injured. These damaged nerve fibers send incorrect signals to other pain centers. The impact of neuropathic pain is profound, affecting the quality of life and daily functioning of patients. This pain is often resistant to the usual pain relievers, necessitating the need for alternative therapeutic strategies.
Symptoms of Neuropathic Pain
- Sharp, stabbing, or burning sensations
- Tingling or numbness
- Sensitivity to touch
- Pain from activities that shouldn't cause pain, like brushing hair
- Muscle weakness
- Pain may be constant or intermittent, and it often worsens at night.
Causes of Neuropathic Pain
- Diseases such as diabetes or multiple sclerosis
- Infection, such as shingles
- Nerve compression or trauma
- Chemotherapy or other medications
- Genetic predisposition
- Sometimes, no apparent cause is identifiable.
Treatment of Neuropathic Pain with Ketamine
Ketamine, traditionally used as an anesthetic, has shown promise in treating neuropathic pain. It works by blocking NMDA receptors in the brain and spinal cord. These receptors are important for transmitting pain signals. Several studies and expert opinions support the use of low-dose ketamine infusions for reducing neuropathic pain symptoms, especially in cases where other treatments have failed.
Benefits of Ketamine in Treating Neuropathic Pain
- Rapid relief from pain
- Reduction in the intensity of pain, even when other medications have failed
- Improvement in overall quality of life
- Potential long-lasting effects after the infusion period
- Lower risk of dependence compared to traditional opioids.
