Waking up in the middle of the night with numbness in the arms and legs may be caused by a lack of calcium, which requires timely, very good, regular and scientific calcium supplementation for relief. It may also be caused by cervical spondylosis, such as sleeping inappropriately at night, so avoid pillows that are too soft and too high, avoid having overhanging places, avoid localized compression of the arms, and do not raise the arms above the head. If the diagnosis is confirmed to be caused by cervical spondylosis, if conservative treatment is not effective, surgery is needed to release the nerve compression. Non-steroidal, anti-inflammatory and analgesic drugs and drugs to activate blood circulation and remove blood stasis as well as neurotrophic drugs can be used, and guidance with acupuncture, tui-na, traction and massage. If there is no relief within a short period of time, it is important to visit a regular hospital and choose the appropriate treatment.
