The muscle contractions you feel is muscle fasciculation or muscle twitch. Twitching is caused by minor muscle contractions in one particular area, or the persistent and uncontrolled twitching of a muscle group in a distribution of a single nerve fiber or filament. Usually they are benign and resolve on their own, but persistent flutter may need following investigations;
1) electromyography (EMG)
2) nerve conduction velocity (NCV)
3) blood electrolytes like calcium, magnesium, potassium, sodium, etc
4) thyroid and parathyroid function tests
5) blood chemistry and complete metabolic profile
The common causes can be;
1) Idiopathic; no cause is ascertained and majority falls in this group.
2) Increased caffeine intake
3) Increased alcohol intake
5) Deficiency in diet and nutrients / minerals
6) Some neurological diseases; uncommon
Please feel free for your follow up questions.
I have not had any increase in caffeine or alcohol. My diet is high in fruits and vegtables as well as calcium via yogurt and cottage cheese. I do not eat any red meat and very little meat products at all. I have had type I diabetes for over 42 years treated with Humulin N insulin and also take synthroid .2MG and Zyrtec for seasonal algeries.
Most of the time I am not even aware that this is happening, but when I am quite deep in thought I can at times actually feel the twitching.
Is there a medical field that would specialize in this sort of thing?
You are very welcome.
The neurologist would be the specialist to handle this. The specialist may contemplate the investigations like EMG, NCV, electrolytes etc as we discussed for ascertainment of the cause.
It is pleasure and privilege assisting you.
