Stuttering and Essential Tremor?
About 4 years ago, I was diagnosed with Essential Tremor, which is a condition that has symptoms similar to Parkinson's Disease, except the tremors manifest during activity, rather than at rest. My tremors are extremely mild compared to many sufferers and most people don't notice I have it unless they spend more than a few minutes in my presence. To give an example of a manifestation, if I use my right arm (most affected) to put a cap on a bottle, the arm threatens to jerk around on it's own, seemingly, and the harder I try to get the cap on, the worse it gets. Threading a needle is all but impossible and once I almost threw a cup of coffee in my own face. If I hold a piece of paper up to read it with that hand, it shakes almost uncontrollably. In fact, the last example is what alerted my coworkers to my condition and a recommendation to see a doctor.
Most recently, I'm having discomfort in my right shoulder. It's not pain exactly, it's a general feeling of discomfort and unease in that shoulder. It's very difficult to explain. I feel like it's almost glowing, if that makes sense. Like something is going wrong with it. Sometimes I fear to hold out my arm, because it feels like my arm will just slip out of the socket. That's a strange sensation to describe but it's very annoying and I don't really want to go back to the doctor.
