Hi jjbxl........I have almost always got cold hands even before i had PD but definitely worse now, i like to dance and people do like to make comments on how cold my hands always are! i joke and just say i don't have enough blood to reach my hands, but they do really get quite icy. My Husband has the same problem though thankfully he does not have any PD and keeps pretty good health, he usually wears fingerless gloves......summer and winter!! even indoors with the heating on!
I wish i could give you an answer....apart from keeping them moving and wearing gloves! sorry
