I have occasional twitches on fingers and toes. Is this a sign of Parkinson's disease?

Hello doctor,

I am a 48-year-old male. A couple of months back, I was diagnosed with a bulging disc in C6 and C7. I had pain and weakness associated with the problem, and after some treatment, the pain subsided. Since then, my left index finger developed a twitch. I am always at rest, and I experience twitching on and off most of the day. Some days I would hardly notice it at all if any. Now my left middle finger is starting to twitch the same as my index finger, and the twitching in my index finger is not the same as before. And I also noticed an occasional toe twitch on either foot before falling asleep at night. I could blame the finger twitching on the disc, but the twitching on the toes on each foot make me feel concerned. I am concerned about the possibility of Parkinson's disease. I researched all I could on the Internet. I do not have any other symptoms associated with the disease. I also tried to figure out the difference between tremor and twitch. It seems Parkinson's tremors are very rhythmic while mine are more sporadic. I have attached a video of my index finger for your review. Please help.

Hi doctor,

Thank you for your response.

Today, my right thumb twitched for the first time like my index finger that I had shared in the video. This was very alarming to me because all other twitches have been limited to my left index and middle finger. I could blame the twitches on a pinched nerve or other causes on the left but now it has moved to the right. It only twitched for about ten seconds and then stopped. I am still worried about the possibility of Parkinson's disease. I have made an appointment with my primary physician for bloodwork.
