Tingling or Numbing
When your body has a low level of calcium, the nerves and muscle tend to be abnormally excitable. This sign is mild and occurs in calcium deficiency in the early stages. If you experience uncontrollable muscle twitching, the level of this mineral may result in severe issues.
There is a way to check for this, and it has to do with cuffing the upper arm with a blood pressure cuff and inflated, which help reduce the flow of blood to that particular hand. If this test results in hand spasms, then it is called Trousseau sign. Typically, it noticed in about 94% of people dealing with calcium deficiency and noticed in as low as 1 percent of people with an average level of calcium. [4]
