For example, pain while sitting is associated with inferior cluneal nerve entrapment, pudendal nerve entrapment, and anococcyeal nerve entrapment. This is dependent on the underlying cause of entrapment and the specific nerves involved. The timing/duration of symptoms may be continuous, intermittent, and/or positional.
The symptom distribution is highly dependent on a patient's neuroanatomy, which may mean that two patients can present differently despite having the same nerve entrapped. For a given entrapment neuropathy, symptoms will only present in the areas innervated by that nerve and distal to the entrapment point. The distribution of symptoms is highly specific to the nerve entrapped and the way the nerve courses and branches beyond the entrapment point. Entrapment of certain pelvic nerves can cause incontinence and/or sexual dysfunction. Motor nerve entrapment may present with muscle weakness or paralysis for voluntary movements of the innervated muscles. They may also be pain-free, such as numbness or tingling. These paresthesias may be painful, such as shooting pain, burning, or a dull ache. Sensory nerve entrapment presents with paresthesias. Symptoms vary depending on whether the affected nerve contains motor and/or sensory fibers. Sacral plexus entrapment or lumbosacral plexus entrapment Posterior femoral cutaneous nerve entrapment Piriformis syndrome Īnterior cutaneous nerve entrapment syndrome Nerve injury by a single episode of physical trauma is in one sense a compression neuropathy but is not usually included under this heading. In some cases, surgery may help to relieve the pressure on the nerve but this does not always relieve all the symptoms. Nerve conduction studies help to confirm the diagnosis. The symptoms affect just one particular part of the body, depending on which nerve is affected. Its symptoms include pain, tingling, numbness and muscle weakness. It is known colloquially as a trapped nerve, though this may also refer to nerve root compression (by a herniated disc, for example). Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by direct pressure on a nerve. Radial nerve compression is an example of nerve compression syndrome Medical condition Nerve compression syndrome
