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. [1]
Dissociated sensory loss is a pattern of neurological damage caused by a lesion to a single tract in the spinal cord which involves preservation of fine touch and proprioception with selective loss of pain and temperature. Understanding the mechanisms behind these selective lesions requires a brief discussion of the anatomy involved.
Central cord syndrome, almost always resulting from damage to the cervical spinal cord, is characterized by weakness in the arms with relative sparing of the legs, and spared sensation in regions served by the sacral segments. [25] There is loss of sensation of pain, temperature, light touch, and pressure below the level of injury. [26]
The loss of the spinothalamic tract leads to pain and temperature sensation being lost from the contralateral side beginning one or two segments below the lesion. In addition, if the lesion occurs above T1 of the spinal cord it will produce ipsilateral Horner's syndrome with involvement of the oculosympathetic pathway.
Experts clear up the confusion on lactic acid, the burning sensation you feel in your legs during hard efforts, how to improve lactate threshold.
Inflammation, erythema, pain and increased skin temperature (3–7 degrees Celsius) around the joint may be noticeable on examination. X-rays may reveal bone resorption and degenerative changes in the joint. These findings in the presence of intact skin and loss of protective sensation are pathognomonic of acute Charcot arthropathy.
The damage may result in loss of feeling, paralysis, weakness, [4] and stiffness in the back, shoulders, and extremities. Syringomyelia may also cause a loss of the ability to feel extremes of hot or cold, especially in the hands. It may also lead to a cape-like bilateral loss of pain and temperature sensation along the upper chest and arms.
Meralgia paresthetica or meralgia paraesthetica is pain or abnormal sensations in the outer thigh not caused by injury to the thigh, but by injury to a nerve which provides sensation to the lateral thigh. Meralgia paresthetica is a specific instance of nerve entrapment. [5] The nerve involved is the lateral femoral cutaneous nerve (LFCN).
