Numbness in the hands and feet is a symptom that often occurs in people’s daily lives. Usually numbness in the hands and feet is eliminated in a short period of time and there is no major problem. However, some people have numbness in their hands and feet that cannot be relieved for a long time, especially people suffering from hypertension, hyperlipidemia, diabetes, cerebral arteriosclerosis, etc., should be more alert. There are many causes of numbness in the hands and feet, so you can visit different departments according to the location and symptoms of numbness, and choose a targeted rehabilitation treatment plan and adopt the necessary preventive measures. Numbness in one limb may be a precursor of stroke. If numbness in one limb and the other side is completely normal, it may be a precursor of stroke. Numbness of the limbs caused by cerebral infarction is usually acute and can be accompanied by symptoms such as speech impairment and dysfunction of half of the limbs, so it is important to seek medical attention from a neurologist in this case. One hand numbness alert cervical spondylosis If it is unilateral arm and finger numbness, it may be caused by cervical spondylosis. Numbness caused by cervical spondylosis is usually chronic and recurrent, accompanied by symptoms such as soreness and stiffness in the neck and shoulder. Long-term low head work, cold neck, pillow cushioned too high, etc., easily cause the onset. With cervical spondylosis, numbness in the lateral upper arm may be due to pressure on the 5th (C5) nerve root of the cervical spine; numbness in the forearm and numbness in the thumb and index finger may be due to pressure on the C6 nerve root; numbness in the middle finger may be due to pressure on the C7 nerve root; numbness in the ring finger and little finger may be due to pressure on the C8 nerve root; numbness in the medial upper arm may be due to pressure on the 1 (T1) nerve root of the thoracic spine. The above symptoms should be given the necessary rehabilitation measures, such as high-frequency, low-frequency, traction, phototherapy and hydrotherapy, after a clear diagnosis, and usually the earlier the rehabilitation treatment, the better the clinical effect. This condition can be seen in orthopedics or rehabilitation. Carpal tunnel syndrome is a condition caused by thickening of the transverse carpal ligament, swelling and stasis of the tendons in the carpal tunnel due to wrist strain, or reduction of the circumference of the carpal cavity due to degeneration and hyperplasia of the carpal bone, resulting in compression of the median nerve, causing numbness and weakness of the fingers. Usually there will be numbness and weakness of the fingers with progressive aggravation. If the numbness of the fingers is aggravated when flexing the wrist, it may be caused by carpal tunnel syndrome. It is common in middle-aged women who are engaged in more household chores such as washing clothes and mopping floors. This condition can go to the orthopedic or rehabilitation department, after a clear diagnosis to apply the necessary high-frequency, low-frequency, phototherapy and hydrotherapy treatment, if necessary, supplemented by orthopedic braces for rehabilitation treatment is more effective. Single leg numbness alert lumbar spine disease If the numbness is unilateral thigh or calf, foot, may be caused by lumbar spine disease, usually chronic, recurrent numbness, accompanied by lumbar pain, discomfort and other symptoms. It is likely to cause onset in cases of prolonged heavy work, strenuous exercise, history of trauma, smoking, cold, and poor posture. Among lumbar spine diseases, it may usually be lumbar disc herniation, lumbar spinal stenosis, or lumbar intervertebral instability, or it may be lumbar spondylolisthesis, calcification of the ligamentum flavum or posterior longitudinal ligament, or even congenital malformations such as isthmic cleft, sacral spine occult cleft, lumbar sacralization or sacral lumbarization. This condition can be seen in orthopedics or spine surgery. Symmetrical numbness should be prevented from diabetic lesions Diabetic-induced peripheral neuropathy often presents with symmetrical pain and sensory abnormalities, with symptoms more common in the lower extremities than in the upper extremities. Sensory abnormalities include numbness, ankylosis, insect crawling, heat, electric shock-like sensation, often from the distal toes up to the knee, and patients have abnormal sensation like wearing socks and gloves. In this case, patients should go to the endocrinology department as soon as possible. Numbness and pain are more than tumors. If elderly people have long-term chronic numbness in hands and feet, which cannot be relieved, they should also consider that it may be caused by malignant tumors. In the advanced stage of tumor, due to the effect of distant parts, it will produce corresponding neurological symptoms, such as numbness, weakness and unstable walking in hands and feet. Therefore, a definite diagnosis can be made only with physical and auxiliary examinations. Women especially need to check the ovaries and breast for early detection of tumor and timely treatment. This condition can be seen in oncology or gynecology. In addition, diseases such as neurogenic diseases, local vascular stenosis of the limbs, Raynaud’s syndrome, varicose veins in the lower limbs, and heart disease may also cause numbness in the limbs, so after excluding the common causes mentioned above, the possibility of other diseases should also be considered. However, some middle-aged and elderly people have numbness in the hands and feet, and may not find the cause after various examinations. In this case, there is no need to be overly nervous, you should relax your tension, maintain a good rhythm of life, and carry out the necessary rehabilitation treatment for cervical spondylosis, stroke, carpal tunnel syndrome, lumbar disorders, diabetes and osteoarthritis of the knee joint under the premise of a clear diagnosis, and the symptoms of numbness will gradually disappear. It is important to note that numbness in the hands and feet cannot be treated purely symptomatically, but the first task is to clearly diagnose and find the cause. Regardless of the cause of the numbness in the hands and feet, you should first go to the hospital for examination to determine whether there is nerve damage. If there are nerve problems, electromyography is required if necessary to further confirm the degree, extent and nature of nerve damage. After the diagnosis is clear, the necessary rehabilitation treatment should be carried out as soon as possible. Of course, if the numbness in the hands and feet is caused by other diseases, the patient should be seen in the relevant department.
