Symptoms of calcium deficiency leg pain include muscle spasm, resting pain, joint pain and other conditions, which require timely supplementation of calcium tablets to avoid adverse consequences. 1. Muscle spasm: after resting at night or getting cold, the symptoms will be more obvious, and there may be persistent muscle spasm accompanied by severe pain. 2. Resting pain: the symptoms may be more obvious when the patient is resting and less obvious when he/she is moving around, and the pain is commonly felt in the heel and the inner side of the calf. 3. Joint pain: The lack of calcium may lead to osteoporosis, resulting in joint pain. Calcium deficiency and leg pain can be treated with calcium supplements, such as calcium chondroitin tablets and calcium carbonate Vitamin D3 tablets. The use of specific drugs need to be under the guidance of a professional physician.
