Hello,
Thank you for your query at DoctorSpring.com
I understand your concern.
Such tremors could be due to :
- Nerve related problems ( Vitamin B12 deficiency )
- Related to Anxiety
- Neurological issues.
Since it has been there for 5 years now, I will advise you to get your b12 levels checked as well as get a CT Scan of the brain and share it with me.
Once I have the reports, I can guide you further.
Regards.
