Jules - My husband, Dick, went through a year or so of shortness of breath, as verified by breathing tests done by his GP. He immediately sent him for other tests, fearing a blood clot in the lungs. Nothing, so the matter was dropped. Neuros aren't particularly interested in this, I've found, and no one seems to want to say it's PD related. No one has any treatment to offer, either. In answer to your question, yes, Dick has internal temors plus restless leg syndrome. For whatever reason, the shortness of breath improved. We can only think it's due to medication, but can't say what would have made the difference. Good luck. Margie cg for Dick, 54/17
