Here's an old post I found with some of the problems you(and almost everyone on here) are having, which involves the thyroid:
The muscle twitches you are describing sound a lot like hypoparathyroidism (undersecretion of parathyroid hormone or PTH). Too little PTH leads to a deficiency of calcium, which causes muscle fibers to "twitch" spontaneously. It is usually caused by some type of damage to the parathyroid glands, such as when thyroid surgery has been done. (The parathyroid glands are located on the posterior surface of the two lobes of the thyroid gland.)There are a couple of very simple tests which may indicate hypoparathyroidism. One is Trousseau's Sign: the hand contracts spontaneously when BP is checked with a cuff on the same arm. The other is called Chvostek's Sign: When the angle of the mandible (jawbone) is tapped, the muscles of the face will spasm. You could almost try that one yourself.Good luck and please re-post and let us know if you find out anything. "I have been experiencing muscle twitching and spasms all over my body for a few months now. It started in my left eye. At first, I would notice it after I sneezed, flinched or got under the shower. Then it started to do it on a more frequent basis. Then I started noticing small twitches in my arms, then my back, then in my legs. By the end of the week I felt them going off every few seconds, randomly, from head to toe."
