Can low blood calcium cause muscle stiffness?

In specific response: Yes.

According to the Merck Manual of Medical Information, Page 738: “An extremely low calcium concentration, below 7 mg per deciliter of blood, may cause muscle aches and tingling, often in the lips and tongue, fingers and feet. Seizures and spasms of the muscles in the throat leading to difficulty in breathing as well as tetany, general stiffening and spasms of the muscles, can occur in severe cases.”
