My son is 18 years old. A couple of years ago he developed

This answer was rated:

My son is 18 years old. A couple of years ago he developed a twitch in the muscle under his eye. He then developed muscle twitches in his arms...looks almost like when a muscle contracts due to electric shock. His legs started doing same later on but not as bad. Now he says his arms and legs hurt, and his fingers tingle a little.

Any ideas?
Welcome to and thank you for your question.This is Dr. Robert, I'm so sorry to hear of your discomfort. I am going to assist you with your question.
First I need a little more information-

Any recent changes in his weight?
Has he been diagnosed with any medical issue?
Does he suffer from anxiety attack?
Does he has any other associated symptoms?

Kind Regards,
Dr. Robert

As far as I can tell, none of those. He doesn't exercise much, and spends a lot of time playing video games.
Dear Customer, Thanks for providing the additional information.

There are few underlying medical conditions, responsible for such symptoms. These are-
1. Benign fasciculation syndrome- It is believed to be an auto-immune response to a viral infection. Many suffers of this disease have noted that onset of their symptoms occurred just after a viral illness or infection, such as the flu. Also, many experience an increase in their symptoms during times of illness.

2. Nutritional deficiencies (vit B12, vit D), Magnesium deficiency.

3. Thyroid hormone imbalance

4. Some neurological diseases, though these are very uncommon.

To make a diagnose, he need to get these tests done-
-Blood electrolytes like calcium, magnesium, potassium, sodium, etc
-Thyroid and parathyroid function tests, Complete blood count
-Blood chemistry and complete metabolic profile
-Nerve conduction velocity (NCV)

As such this should not be left ignored, and have to be checked by doctor. I would recommend that he should be seen by his primary doctor for evaluation and get it managed.
