What causes my arms to fall asleep at night?
When one or both of your arms seem to fall asleep as if they are going numb, a variety of causes may be responsible, some are benign or some actually needs medical treatment. Often it may because of your sleeping position. You might be lying on your arm in a way that puts pressure on a nerve in a limb. But if you are diagnosed with some illnesses, such as diabetes, Vitamin B Deficiency. That’s all I know, coz I am also experiencing it.
