I was diagnosed about 18months ago with mild PD too. I take sinemet which works well for me.
I don't have symptoms like yours but amongst a range of other symptoms I do have an interesting variety of shakes in different parts of my body. They come and go and are not always visible. Sometimes I can lessen them by relaxation techniques or by distracting myself with a task or puzzle. It doesn't always work though. But then at least my shakes come and go so at least they're not permanent yet.
It seems that there's a huge range of symptoms in PD. Daffy
