It is possible that it could be Essential tremor
at your age of 51. However, we need to rule out early onset Parkinson's disease as well. Please get back to your Neurologist
and discuss about this option.
Continue to take Vibrania; it will help you. Neurotropic drugs like Neurobion
forte are very helpful. It is similar to Vibrania.
If Parkinson's disease is confirmed, then you may be treated accordingly. The tremors in this are static, i.e. present at rest and they disappear while doing a task.
I hope this helps you in a way.
I wish you good health.
