On Call. I am a subscriber to Harvard Men's Health Watch, but I am writing about my wife, not myself. She's only 58 and she's always been healthy, but over the past year she's been bothered by shaking and trembling in her hands, particularly when she's pouring tea or eating dinner. Her doctor gave her a blood pressure pill, but she's never had high blood pressure. Does she have Parkinson's? Should I take her to a specialist?
