I just 89 years old, very fit, no aches or pains but recently I have woken in the morning with internal shaking, it seems to be in the upper part of my body. It last for about five mins. I have normal to low blood pressure. I sufffer from mild depression which comes and goes. I am very lucky as I seem to be able to do anything BUT run. At the moment I am with depression, time of the year? Not wanting social interaction nor cope with committed things to do. I had this for a short time 15 years ago when coping with a deep depression. Thanks for taking my question.
