Early on in parkinson's can the tremble come and go in one finger? or when you get it is it consistet non sstop even early on in the process?

Pill rolling: The classic early sign of parkinson's disease is "a pill rolling" type tremor- often very transient in the early stages of the illness.

Yes but...: You are very young to have parkinson's disease, so it would be very unusual. A neurologist would be able to offer their thoughts after visiting with you and conducting an easy examination. Please dont hesitate to request to see one if you have concerns.
