Several possible causes of neuropathy can lead to cellular malfunction involving nerves and neurotransmitters. These can include nerve-related diseases, drug and alcohol use, vitamin B deficiency and toxins. The resulting cellular dysfunction can cause an increased sensation of pain to originate from a particular area in the body, states MedicineNet. Additionally, the spinal cord can be adversely affected by a loss of normally functioning cells, which can cause the perception of pain despite external stimuli. In the brain, the ability to prevent pain signaling can be affected by a stroke or other brain trauma. Pain can persist over time due to the occurrence of further cellular damage.

Medications used to treat neuropathic pain can include antidepressants, anti-seizure and heart arrhythmia medications. Topical medications such as lidocaine and capsaicin can benefit some patients, reports MedicineNet. However, to cure neuropathic pain, the underlying cause must be addressed. In some cases, neuropathy is reversible and the nerves heal over time.
