Glossopharyngeal neuralgia is a condition that affects the glossopharyngeal nerve, a cranial nerve in the neck. This results in a severe sharp, stabbing pain in the back of the throat and tongue, the tonsils, and the ear.
Following an attack of shingles up to one in five people go on to develop Postherpetic neuralgia in the site previously affected by the shingles. This presents as a continuous stabbing, burning pain. Treatment for postherpetic neuralgia is usually with anti-depressant or anti-convulsant medication such as amitryptiline or gabapentin for instance.
Trigeminal neuralgia is a particularly painful condition which is characterised by sudden, short attacks of facial pain often described as shooting or electric shock type pain. Trigeminal neuralgia causes include, most commonly, compression of the trigeminal nerve, or some other problem with the nerve itself perhaps caused by a tumour or cyst.
The mainstay of Trigeminal neuralgia treatment is an anticonvulsant medication such as anti-conviulsant drugs such as gabapentin or pregabilin which help to relieve the nerve pain by slowing down the electrical impulses in the nerve and reducing their ability to transmit pain signals to the brain.
