Brief Answer:
Do not need to do any thing for now

Detailed Answer:
Hello madam,
I have read your query and I had good experience with dealing such problem. This type of muscle twitching is called fasciculations and it can be due to following.
1.Anxiety
2.High thyroid level
3.High blood pressure
4.Idiopathic
As you have not mentioned any problem like high blood pressure or thyroid so I assume that you are having idiopathic where there is no obvious cause. In these cases there is no active treatment needed. With in a week or so this fascicualtion will go by its own.
If it increases or cause more pain then you can start taking Amytryptalin tablet 10 mg after discussing with a neurologist.
I hope this answer will be helpful for you. Let me know if there is any other followup questions.
Thanks.

Brief Answer:
I think thyroid can be the cause

Detailed Answer:
Hello mam,
I would suggest you to repeat your thyroid test and along with that you can also get serum B 12 estimation. Very rarely lack of this vitamin can also cause such muscle contraction. Please share your investigation reports with me.
thanks.

Brief Answer:
One month is a long time

Detailed Answer:
Hello,

One month is a long time because thyroid hormone has diurnal variation and it can change at any time, so I would suggest you to repeat the test. Some time there is sudden increase of hormone due to stress, anxiety, lack of sleep.

Other option is wait for 5 days and if your condition persists, I would suggest you repeat the test.

Thanks.
