Botulinum toxin A relieved neuropathic pain in a case of post-herpetic neuralgia.
Botulinum toxin type A (BTX-A) has been widely used in many clinical disorders including migraine, cervical dystonia, etc. The use of BTX-A in neuropathic pain, however, is uncommon, and the application of the anti-nociceptive effect of botulinum toxin is emerging. Here we report a case of an 80-year-old man who suffered from severe pain of post-herpetic neuralgia which was refractory to the usual therapies. However, this neuropathic pain was dramatically relieved by multiple BTX-A injection and the pain relief lasted 52 days.
