Hello,Hoping to get some input from others.My main symptom is the feeling of internal tremor/shakiness in my left arm. (I originally started about four months ago with some twitching in the hands but for the last six weeks it seems to have just moved to my arm.) My left hand fingers have a fine tremor too. I have read about hot spots on this forum but most people seem to describe them as a localized area of twitching that may last for weeks/months, rather than tremors. Does anyone have the internal tremor feeling localized to one area for a long time? Do you think the fact that my symptoms are localized is more worrisome than if the twitching/tremors were moving around my body randomly?thanks in advance for your input.Wendy
