Increased sweating after cold is one of the symptoms of spinal cord cavitation. Spinal cord cavitation is a bizarre sweating phenomenon of increased sweating after cold, accompanied by decreased temperature, hyperkeratosis of fingertips and nails, atrophy, and loss of luster. Due to the loss of pain and temperature sensation, burns and bruises and trauma are likely to occur. Late stage patients develop urinary and faecal disorders and recurrent urinary tract infections. The age of onset is 31 to 50 years old, and it is rare in children and the elderly. There are more males than females, and a family history has been reported. The clinical manifestations of spinal cord cavitation are threefold, and the degree of symptoms is strongly related to the early and late development of the cavity. The disease generally progresses slowly, and the early symptoms appear in a segmental distribution, affecting the upper extremities first. When the cavity expands further, the gray matter in the medulla and the white matter conduction bundles outside it are also involved, and conduction bundle dysfunction occurs below the cavity cavity. As a result, the symptoms are limited and mild in the early stage, while in the late stage, the symptoms are widespread and even paraplegic. To prevent increased sweating after cold, we should pay attention to the following points: 1. Maintain an optimistic and happy mood Strong long-term or repeated mental tension, anxiety, irritability, pessimism and other emotional changes can make the balance of cortical excitation and inhibition process out of balance, so that the muscle jump aggravates, so that the development of myasthenia gravis. 2, reasonable diet Keep the digestive function normal. Spinal cord cavitation myasthenia patients to maintain normal digestive function, reasonable deployment of dietary structure is the basis of recovery. Patients with spinal cord cavitation myasthenia require high-protein, high-energy dietary supplements to provide substances necessary for the reconstruction of nerve cells and skeletal muscle cells to enhance muscle strength and muscle growth. Early adopts high-protein, vitamin-rich, phospholipid-rich and trace element foods, and actively cooperates with medicinal diets, such as yam, coix seeds, lotus hearts, Chen Pi, prunus seeds, lily, etc., prohibits spicy foods, and abstains from smoking and alcohol. For patients in the middle and late stages, semi-liquid and liquid food with high protein, high nutrition and rich in energy should be the main food, and less and more meals should be used to maintain patients’ nutrition and water-electrolyte balance. 3, pay attention to the prevention of colds, infections spinal cord cavitation myasthenia patients due to their own immune function is low, or there is some kind of immune deficiency, once the cold , the condition is aggravated, the course of the disease is prolonged, myasthenia gravis, muscle jump aggravated, especially ball palsy patients prone to complications of pulmonary infection, if not timely prevention and control, the prognosis is poor, and even endanger the lives of patients. Gastroenteritis can lead to intestinal strain dysfunction, especially viral gastroenteritis has different degrees of damage to the anterior horn cells of the spinal cord, thus making the patient’s muscle jump aggravated, muscle strength decreased, recurrent or aggravated.
