[|Human|] Chronic Lower Back Pain -Vicodin (2+ years) Mood Disorder - Lithium (2+ months) Anxiety - Valium - (2+ years) Am having occasional involuntary hand tremor-more like a jerking motion. Sometimes right hand/arm sometimes both hands/arm. Began about 6 months ago. What may be happening?
[|AI|]  Hi, The hand tremors may be essential tremors, that is those without any known cause. They may also be due to anxiety and in that case, would be manifest only when you are anxious. Lithium can also cause tremors, but you mention that the tremors started before you were put on lithium. If no cause can be found, I expect your doctor would treat these on the lines of essential tremors by prescribing beta blockers like propranolol. Best wishes.
