Every patient has their own Parkinson’s. My tremor had only recently manifested. I’ve had Parkinson’s for 6 years by diagnosis ( much longer in reality). Tremor free.

My symptoms were mostly non-motor. Invisible, but very real. However, like you I have severe balance issues.

I have found I can avoid falling by being conscious of every movement I make. Regular people can get by on muscle memory. We need to pay attention to every movement we make.
