Are Tremors In Fingers,depression And Skin Bleeding Issues Suggestive Of Parkinson S Disease?

My 63 year old husband just retuned from an appointment with a surgeon to discuss his up coming back surgery. The surgeon has scheduled an appointment for him this afternoon to be evaluated for Parkinson s disease based on sight tremors in his fingers and abnormalities in his gait. He has been increasingly depressed, with unexplained and untreatable nausea on a daily basis. Mostly dry heaves. His skin bleeds easily and bruises terribly with minor injuries or bumping. Could Parkinson s be a possibility.we would greatly appreciate your response.
