Dearest PN Angels,
My [size=14pt]
CT Scan [/size]with contrast dye
showed no abnormalities of my carotid arteries, including branches above my neck.
So my limb shaking is not from temporary occlusion of the carotid artery (by head position, etc) leading to loss of oxygen to the brain, leading to Temporary Ischemic Attack, causing the limb shaking. This is a real syndrome and must be found and corrected as it can be dangerous, even fatal.
My [size=14pt]
EEG[/size] this morning was perfectly
normal. YES!
So why do I have limb shaking, specifically my left arm and hand?
I've been doing some searching and I've come up with a possible match to:
Essential myoclonus occurs in the absence of epilepsy or other apparent abnormalities in the brain or nerves. It can occur randomly in people with no family history, but it also can appear among members of the same family, indicating that it sometimes may be an inherited disorder. Essential myoclonus tends to be stable without increasing in severity over time. In some families, there is an association of essential myoclonus, essential tremor, and even a form of dystonia, called myoclonus dystonia. Another form of essential myoclonus may be a type of epilepsy with no known cause.
Myoclonus Fact Sheet
Myoclonus refers to involuntary contraction of the muscles: hiccups are a common example, and the sudden jerking just as you're falling asleep.
My younger son has had essential tremor of his left hand since his early 20's. It is quite marked, but has not progressed in severity. He is now 46.
I had three episodes yesterday of the tremor of my left hand and arm, one quite strong and two very mild ones.
So perhaps essential or idiopathic myoclonus, which is purely descriptive.
I can live with this, and am so glad horrid things have been ruled out!
Hugs, ElaineD
