In the precentral area where the homunculus rests, it is known that hand and shoulder areas overlap the trunk area. And the area of the thumb overlaps that of the upper part of the tongue. There is a published case in which stimulation in the thumb led to a referred sensation in the upper part of the tongue.
Paresthesia, also known as pins and needles, is an abnormal sensation of the skin (tingling, pricking, chilling, burning, numbness) with no apparent physical cause. [1] Paresthesia may be transient or chronic, and may have many possible underlying causes. [ 1 ]
This prevents sensation in the area associated with the nerve. In the case of the trigeminal nerve, this is the face, meaning hypoesthesia of the face is experienced. Excision is the only effective treatment of trigeminal schwannoma, though this may not treat the associated hypoesthesia if damage has already occurred.
Dysesthesia can include sensations in any bodily tissue, including most often the mouth, scalp, skin, or legs. [1] It is sometimes described as feeling like acid under the skin. Burning dysesthesia might accurately reflect an acidotic state in the synapses and perineural space.
A burning sensation in the mouth may be primary (i.e. burning mouth syndrome) or secondary to systemic or local factors. [1] Other sources refer to a "secondary BMS" with a similar definition, i.e. a burning sensation which is caused by local or systemic factors, [16] or "where oral burning is explained by a clinical abnormality". [17]
Lesions which destroy lower areas of the spinal trigeminal nucleus (but spare higher areas) preserve pain-temperature sensation in the nose (V 1), upper lip (V 2) and mouth (V 3) and remove pain-temperature sensation from the forehead (V 1), cheeks (V 2) and chin (V 3). Although analgesia in this distribution is "nonphysiologic" in the ...

Cheiralgia paraesthetica (Wartenberg's syndrome) is a neuropathy of the hand generally caused by compression or trauma to the superficial branch of the radial nerve. [1] [2] The area affected is typically on the back or side of the hand at the base of the thumb, near the anatomical snuffbox, but may extend up the back of the thumb and index finger and across the back of the hand.
