If the patient has leg numbness while sleeping, the following treatment measures need to be taken: 1. It is recommended that the patient should sleep flat on a hard bed, that is, in a supine sleeping position. In addition, the sleeping mattress should not be too soft, requiring 2-3 layers of bedding on a light bedpan is enough to maintain a certain level of hardness. If a mattress is used, the firm side should be used. In addition to this, patients should try not to take side lying, and if they must lie on their sides, they can put a softer pillow between their legs. If the patient can afford it, a small pillow can be placed under the waist to keep the waist in an over-extended position. 2, if after such treatment, the symptoms of leg numbness do not have any relief, the patient should go to the orthopedic department of a secondary or higher hospital as soon as possible, to clarify the cause of this symptom, and then targeted treatment. In the case of lower limb numbness, there may be peripheral neuropathy or lower limb vasculopathy, but in either case, early treatment is needed. For peripheral neuropathy, surgery may be required to relieve nerve entrapment, such as removal of a herniated disc. For vascular lesions, some interventional procedures may be required to remove the obstructing material from the blood vessels.
