Hello !
I read carefully your question and understand your concern.
I would like to know your age and if you have a family history for tremor.
There are different causes of tremor.
As far as I understand from your description, yours is an intentional tremor, which gets worse when you try to reach for the target.
In a young patient I would think about a metabolic cause like
hyperthyroidism. While in older patients I would think about
essential tremor, a degenerative disease or a stroke. But the gradual beginning of your tremor rules out a possible stroke. A positive family history for tremor would be in favor of essential tremor diagnosis.
Sleep apnea can cause tremor in the hands during the day, but it would improve with the good treatment of apnea.
So I would recommend you to consult with the
neurologist and have a full blood work and the
thyroid function tests.
A brain MRI may be helpful if the above tests result normal.
Hope to have been of help!
Greetings!
Dr. Abaz Quka
