Ted, My son, too, at age 27 seems to have a tremor in both hands. His step dad was diagnosed with PD last year, so we can't blame heredity. He went to his general physician who said it might be stress or a familial tremor, but said if he was concerned he would refer him to a neurologist. The same neurologist that treats his step dad also did a work up on my son--blood work, hand-eye coordination drills, etc. He said all look fine and he should wait 6 months to see if just goes away. The neuro says all people have tremors--it is a normal human bodily condition, but some are more active than others. My son is worried it is psychosomatic. We are playing the waiting game. Keep us informed. Linda John 55/1yr
