Hi Proudest Mom,
I too, experienced the out of breath. I would guess it is a combination of stress, dystonia off the diaphram and Parkinsonoism symptyms. Eventually it will no longer be a problem when your PD decides to strike a different part of your system. If it becomes severe enough don't hesitate to dial 911. A option you might try, and it may sound odd, is Benedryl. My son, the paramedic said it is the first choice for ER physicians when PD patients come through the door. Worked for me sometimes.
Blessings,
Vicky
