Hi @gigiraj , I have some experience with finger twitching! I'm older now, but when I was a young thing in my 20s, I was into cycling long distances, and I typed all day at my job. My thumb would twitch, especially in the evening when I was trying to relax and fall asleep. I never asked a doctor about it ever! I eventually developed carpal tunnel in my wrist though. These days, Id say I overtype on my smartphone and stress my joints, but my fingers don't twitch like they used to.

I had a doctor tell me that things aren't treated unless they are an impairment. I never considered my finger twitching in the evening an impairment. I used to avoid doctors, stay away from them believe me! Unless you have an impairment.

one thing you could try is getting one of those DNA tests offered, they are around $100 or so, and the DNA test will tell you if you have the DNA for parkinson's disease. Cheaper than an MRI. That's what I did, one company told me I don't have DNA for parkinsons, alzheimer's or the BRCA gene, I was relieved to hear those things.

Don't worry, don't fret. my finger twitched from overuse, including overuse of a keyboard.
