Finger Drop?!?!

So, today I am trying to sit at home and catch up on some apprenticeship work as I’m falling behind a little. I am casually typing and typing away on the laptop and then realise that I am constantly triggering the mousepad response without pressing it. I have realised this is due to mi little finger and ring finger on my right hand drooping and I can’t keep them raised!! I have this with food drop when excessive walking and exercising but I did not know there was such a thing as finger drop!! Please tell me this is an actual thing that happens to others and not just me?
