Nerve entrapment is caused by direct pressure on a single nerve and creates pain, numbness/tingling, and reduced sensation in the affected limbs.
A nerve can become trapped (or compressed) by repeated external forces such as continuous postural positions like resting your elbows on a table.
The symptoms will vary depending on which nerve is affected and how severe the entrapment is.
Treatment for a nerve entrapment includes joint mobilization and stretching exercises. Therapeutic ultrasound may also be applied to reduce any inflammation in the surround muscle.
