Introduction: Leg pain in the morning is mostly caused by calcium deficiency, cold and local nerve and blood vessel compression. Usually, you can properly supplement calcium, get more sunshine, pay attention to local warmth, and also pay attention to the changes of sitting posture and sleeping posture to avoid nerve and blood vessel compression. You can also do local muscle hot compress and massage to strengthen local blood circulation, which will generally be good. If it has not improved, you should go to the hospital for examination and treatment. Wish you good health.
