... expecting something?

Well, not at, not Parkinson's, because I kept going to my family doctor saying, "Something's wrong with me." And, and as a painter, I, I was, I couldn't, couldn't paint properly, and I kept being told repeatedly over, I guess it was a year and a half, I, I kept going back every six months, "I'm just aging." Uh, and finally, I did see a neurologist who, based on how I walked, 'cause I was, uh, I didn't move my right arm, it was frozen against my body, and my hand was shaking.

I was slightly dragging my right foot.

I guess it would be called drop foot, and I had very little expression on my face.

And, and then he said, "You have Parkinson's disease." And- I, I was in complete shock.

I, I had been prepared for perhaps an essential tremor as a diagnosis or a pinched nerve, but never Parkinson's.

No one in our family had had that diagnosis.

... could you explain, explain it to our listener what it is and how it came about?
