Various Neurological Symptoms

[Rick T]

I am a 57 year old male teacher and always have had somewhat  shaky hands. About five years ago many elementary students commented that I was constantly shaking.   Since I have been on heavy Wellbutrin doses for years and some lithium  I assumed at first they meant just my hands.  No adults ever commented about it and I didn't think much about it because I didn't notice anything.  A few years ago my left hand developed a twitching, especially in the thumb and ring finger.  My other hand started months after.  Putting weight on my arms causes various tremors now in my arms and hands.  Doing any upper body lifting or short upper body exercise exhausts me for a day.
Now I have had jaw tremors CONSTANTLY for a month.  190 beats a minute.  My teeth chatter if I put them near each other so with the jaw pain I have been wearing a night mouth guard.  If my mouth is open somewhat the tremor seems to be alleviated quite a bit.  My 92 old father developed Parkinsons's a few years ago and my mother  apparently has had essential tremors for 25 years but hers in mostly with moving her hands. She won't talk about it.  She doesn't take L-Dopa.   Dealing with depression is terrifying enough but now the jaw tremors take it to another dimension.  I fear all the possiblilities and will see a doctor in the future.
I know that it ridiculous and unwise to diagnose myself but I fear Parkinson's or even worse.  Does anyone have any insights especially about the jaw tremors.
Thanks,  Rick

Thanks for your support.  The battery of tests and even the eventual uncertainties looms but I will go in the near future.  I appreciate your taking the time to write.

Hi Rich,

Your symptoms could be due to Parkinson's disease. Presence of 'Jaw tremors' in Parkinson's disease have been reported, even isolated Jaw tremors, without involvement of fingers, hand or foot has been reported.

The other condition, which needs to be ruled out is 'Essential (benign, familial)Tremors', which can be mistaken for parkinsonian tremors. The family history of tremors is more common, alcohol in small quantities may improve these tremors and usually other neurological signs are lacking.

I will suggest you to take an appointment with a neurologist.
