John, My mother Joyce (68/13 months) finds tightness in the chest one of her most bothersome symptoms. Along with this is a shortness of breath and rapid heartbeat. She has discussed this with her doctors, but no one seems to know how it relates to PD. Since taking Requip (along with Paxil and a little SInemet), the symptoms have gotten better. Good luck and stay well. Debbie White [log in to unmask]
