Pain caused by nerve injury or dysfunction is known as neuropathic pain, and anticonvulsants like gabapentin and pregabalin are frequently used to treat it. These drugs mitigate pain signals by lowering nerve cell excitability.

THC and CBD are two of the many cannabinoids that can be extracted from the cannabis plant. They alleviate discomfort and inflammation by interacting with cannabinoid receptors in the central nervous system and brain.

Opioid medicines like oxycodone and hydrocodone are used for chronic pain management and are quite potent. There is a substantial danger of addiction and overdose with these drugs, therefore they should only be taken if nothing else has worked.
