I am 66 and have had hand tremors since I was was in nursing school in my twenties and learning to give patients injections. Whoa! Patients were somewhat concerned that this shaking nurse was going to give them a shot. Really? But I just went ahead with what I had to do and made a joke of it or gave reassurance to the patient.

Tremors are much worse when I am afraid or angry. A neurologist prescribed propranolol for me and it helps some, but if I take too much my blood pressure falls out. Its not a big problem and doesn't keep me from living my life. Some of my friends in their 70's tremble quite badly and can't write legibly. One person had a little brain surgery that helped quite a bit.
I hope you will explore some techniques to learn to quiet your mind and body; that could help; maybe not. When/if my trembling gets worse I'll try meditation again, yoga, and other non-drug solutions. I do understand and wish for you to accept your challenges.
