Joe, I'm not an MD so I shouldn't comment on your mom's health except to say that I don't think it is unusual for someone's "other" symptons to be more active during and following a medical crisis like a hip replacement, especially if your mom is the stoic type. A hip replacement is major surgery even if they are discharged from the hospital within 2-3 days.Essential tremor does respond negatively to stress both of the physical and emotional kind. And I'm sure her diabeties may be contributing to her generally unsettled state. One other note and this is personal; I had a diagnosis of Complex Familial Tremor{A slight variation of Essential Tremor] since I was a little kid and wasn't diagmosed with PD until I was 44. Some times it takes a long time coming but with a competent Neurologist good nutrition,regular exercise, the right medications,a supportive family and a sense of humor she can expect to live for many productive years regardless of the eventual diagnosis. I wish her and you and her other family members the best of luck. MY VERY BEST George Lussier[[log in to unmask]] [log in to unmask]
