Thank you for the information,
Jerks can be from different factors.
Seizure or epilepsy needs to be ruled out.
So doctor has taken EEG.
There can be different causes too.
Dehydration or electrolyte changes can be factors.
Gentle massage, application of warm or cold can help.
It can be associated with excessive anxiety, fatigue, vitamin deficiency, caffeine intake etc
Please avoid those factors if you have any.
However, you should inform your doctor about the new symptoms.
Take plenty of fresh fruits & vegetables which would help in vitamin & mineral deficiency.
I hope this information helps.
If there’s anything else I can do, please let me know.
If you are satisfied, please rate my answer as good or excellent.
