Are you stressed or anxious.
For me, that is almost like a nervous tic, when I am stressed.
Please see your doctor and get his opinion.

Please check a specialist surgeon. I am saying this because my friend had the same symptom. He was admitted to hospital and all the test was done and found a brain tumor. It's just a matter of preparation
I am not saying that what you have . Please check the doctor. I will be praying for you
God is good all the time
AMEN

Praying

Both anxious and stressed as well.
