These paresthesias may be painful, such as shooting pain, burning, or a dull ache. They may also be pain-free, such as numbness or tingling. Motor nerve entrapment may present with muscle weakness or paralysis for voluntary movements of the innervated muscles. Entrapment of certain pelvic nerves can cause incontinence and/or sexual dysfunction. [2]
Peripheral neuropathy may be classified according to the number and distribution of nerves affected (mononeuropathy, mononeuritis multiplex, or polyneuropathy), the type of nerve fiber predominantly affected (motor, sensory, autonomic), or the process affecting the nerves; e.g., inflammation (), compression (compression neuropathy), chemotherapy (chemotherapy-induced peripheral neuropathy).
