Welcome to NeuroTalk.
It sounds to me like stress related body tremors. They are somewhat common to the mTBI (mild Traumatic Brain Injury) community. I get them in my hands when I am under stress and need to use my hands.
I also tend to get them in a jerking format when I try to go to sleep. I take Neurontin (gabapentin), an adjunct anti-seizure med and it helps. I also started taking Turmeric supplements (circumin) a few months ago and even the break through tremors have stopped.
There are some foods to avoid. Caffeine, MSG, artificial sweeteners (aspartame, Equal, Nutrasweet, Splenda, sucralose) are excitotoxins that cause nerve cells to misfire. B-12 and folic acid help protect nerve cells.
What is your diet like? If you keep a journal of your food intake, you will likely find a link to foods that help and foods that make it worse.
My best to you.
