Yes Earl has the same symptoms and only at night when he gets less medication.

Must need a pulmonary function evaluation test spirometry .it may determine how good you’re breathing

I was diagnosed with PD on 7/18/07. I have Stage 3 PD I have taken many medications and i still take meds. I d0 fall a lot.

Often in the evening before we go to bed, my husband complains there's no air circulating in the house and he's having problems breathing although the temperature is good and we may have windows open (if not humid). I try to calm him down (he gets anxious). For whatever reason it's only at night. Usually when I turn the house fan on and he "feels" the air he's much better. I suppose being tested as suggested above is still a good idea.

I read an article about Parkinson's Wearing Off periods and it said that trouble breathing is also a side effect of "off" time. Best to check pulmonary ability as well. My hubby has the same thing.
