Neuropathic pain is the sensation of pain due to abnormal discharges of impaired or injured neural structures in the peripheral &/or central nervous system.
It is characterized by hyperesthesia, hyperalgesia and allodynia.
Common neuropathic pain syndromes are central neuropathic pain, painful diabetic peripheral neuropathy, postherpetic neuralgia, trigeminal neuralgia, postsurgical neuropathic pain, HIV-related neuropathy, lumbosacral radiculopathy and complex regional pain syndrome.
Treatment with intravenous immunoglobulin (IVIG) offers significant pain relief in patients with painful diabetic polyneuropathy (DPN) resistant to standard therapies, without deleterious side effects, according to the results of a trial.
Delivering high-voltage pulsed radiofrequency of dorsal root ganglion via a multifunctional electrode yields significant pain relief and may prove valuable in the treatment of chronic lumbosacral radicular pain with neuropathic features, according to a recent study.
