[1] The most familiar kind of paresthesia is the sensation known as "pins and needles" after having a limb "fall asleep". A less well-known and uncommon paresthesia is formication, the sensation of insects crawling on the skin.
Clinical diagnosis can often identify compression neuropathy on signs and symptoms alone. While there are variations in how nerves course and branch, the anatomical territory of major nerves do not change from patient to patient. Some forms of nerve entrapment can have characteristic symptoms, such as sitting and pudendal pain.
Common manifestations of sensory issues include numbness or painful sensations in the arms and legs, abnormal sensations like "pins and needles," and heat intolerance. [5] Pain experienced by individuals depends on the severity of the polyneuropathy. It may be dull and constant in some individuals while being sharp and lancinating in others. [4]

It is formed in the axilla by a branch from the medial and lateral chords of the brachial plexus, which are on either side of the axillary artery and fuse together to create the nerve anterior to the artery. [citation needed] The median nerve is closely related to the brachial artery within the arm.
It can occur when a person falls asleep while heavily medicated and/or under the influence of alcohol with the underside of the arm compressed by a bar edge, bench, chair back, or like object. Sleeping with the head resting on the arm can also cause radial nerve palsy. Breaking the humerus and deep puncture wounds can also cause the condition.
There are a number of hypotheses regarding the basis of occlusal dysesthesia. Some researchers believe the disorder is a psychological one, while others believe it to be a psychosomatic disorder. [3] Joseph Marbach hypothesized that the symptoms were rooted in psychiatric disorders. Marbach suggested that occlusal dysesthesia would occur in ...
