Hypoesthesia or numbness is a common side effect of various medical conditions that manifests as a reduced sense of touch or sensation, or a partial loss of sensitivity to sensory stimuli. In everyday speech this is generally referred to as numbness.
Reactive hyperaemia, which occurs when blood flow is restored after a period of ischemia, may be accompanied by paresthesia, e.g. when patients with Raynaud's disease rewarm after a cold episode. [3] Cases of paresthesia have also been reported at varying frequencies following anthrax, [4] flu, [5] [6] HPV [7] and COVID-19 [8] [9] vaccine intake.
Tingling 'whiteness' or numbness in the fingers (blood vessels and nerves affected): This may not be noticeable at the end of a working day, and in mild cases may affect only the tips of the fingers. As the condition becomes more severe, the whole finger down to the knuckles may become white.
Raynaud syndrome, also known as Raynaud's phenomenon, is a medical condition in which the spasm of small arteries causes episodes of reduced blood flow to end arterioles. [1] Typically the fingers, and, less commonly, the toes, are involved. [1] Rarely, the nose, ears, nipples, or lips are affected. [1]
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).
Sensory loss can occur due to a minor nick or lesion on the spinal cord which creates a problem within the neurosystem. This can lead to loss of smell, taste, touch, sight, and hearing. In most cases it often leads to issues with touch. Sometimes people cannot feel touch at all while other times a light finger tap feels like someone has punched ...
Ulnar neuropathy at the cubital tunnel is diagnosed based on characteristic symptoms and signs. Intermittent or static numbness in the small finger and ulnar half of the ring finger, weakness or atrophy of the first dorsal interosseous, positive Tinel sign over the ulnar nerve proximal to the cubital tunnel, and positive elbow flexion test (elicitation of paresthesia in the small and ring ...
Dysesthesia may be caused by a thalamic stroke involving the ventral postero-lateral (VPL) nucleus. It's typically seen in Dejerine-Roussy syndrome with hemi-sensory loss and severe dysesthesia of the affected area. Fibromyalgia may cause dysesthesia in all areas of the body, but mostly the extremities. [medical citation needed]
