what does that mean is that a indicator of a greater health issue. she is a 55 year old smoker.My mother was trying to control my camera her hand was shaking uncontrollably and involuntary ?
Could mean lots of things. If she hadn't eaten recently should be having hypoglycemia. It could be signs of arthritis, parkinsons, MS, and a variety of other neurologic disorders. It could just be nerves - like when you are nervous.My mother was trying to control my camera her hand was shaking uncontrollably and involuntary ?
It could be a sign of a few things, anxiety or m.s., but she will have to go get testing to know for sure if it really is anything at all.
it's called Parkinson's disease-it's where your body has uncontrollable jerky movements that get worse and worse until you can no longer control your own body, even though your brain remains perfectly normal. although it could also be old age and frailness. hopefully it will pass. a famous actor, Michael J. Fox, has parkinson's disease and only noticed it when his pinky, yes only one pinky, was shuddering. unfortunately there is no cure, but there is a research fund founded by Michael that you could look at, not to mention medicine that can help slow down the process and control it.
