Neuropathic pain is a type of pain generally caused by damaged nerves in the body. This damage may have resulted from a medical condition like diabetes, exposure to a toxin, alcohol, or previous surgery. Because the nerves are damaged, pain is not felt the same way as other types of pain.
Unlike pain from an injury, neuropathic pain can happen from normal, light touch, such as from clothing brushing against skin. This leads to feelings of pain that can be described as “burning”, “shooting” or “tingling”. Every person experiences neuropathic pain differently. Neuropathic pain can feel constant, come and go, or it can change in intensity.
Can neuropathic pain be treated or cured?33. Watson P. Neuropathic Pain. https://www-e-therapeutics-ca.login.ezproxy.library.ualberta.ca/search. Updated May 2017. Accessed January 13, 2018.

In most cases, neuropathic pain cannot be cured. However, the pain can be managed.
The main goal of treating neuropathic pain is reducing pain to a realistic level that allows a patient to live comfortably. We are rarely able to eliminate the pain entirely.
