A mononeuropathy (as its name suggests) is a neuropathy of one single nerve. Symptoms will usually be confined to the region of the body that the nerve innervates and will only affect areas below the level of the lesion (if there is a lesion)
Common causes of a mononeuropathy include:
- Nerve compression syndromes e.g. carpal tunnel; cubital tunnel; herniated spinal disc (and sciatica) etc
- Infection- usually herpes zoster but can be caused by other local infection e.g. bone/soft tissue
- Vascular causes e.g. peripheral arterial disease (ischaemia of the nervous tissue supplied by the artery involved)
