my mother seventy eight year old, in the past 6 months, she alway shake her hands, can t hold a cup firmly. sometime her hands and arms can t stand steady when she wants to touch something. At the begining, I thought she didn t have enought nutritional to cause this problem, so I gave her a cup of soup (boil with one pound of meat with ginger only, she drunk the soup without eating the meat), she felt better and stop hand shaking, but several month later, this method cannot improve her hand shaking and still keep shaking while eating. This time, I brought her to have body massage, twice every week,, but the body massage treatment can help her stop hand shaking for three days only. I am afraid her health condition, is this mean her health getting worse? Is there anything I can help my mother to stop her hand shaking?
