I honestly cannot thank each of you enough for all of your help and guidance - it is greatly appreciated! I've decided that what I suffer from is more psychological then physical and that is what I need to overcome. From what research I've done, it is normal for there to be some physical movement when one stretches out their arms. Muscles twitch and move in an effort to maintain a fixed position and that causes our arms and fingers to tremble and shake. The more stress on your arm, the more it's going to work to attempt to maintain that fixed position.
I've experimented with my trembling and seen that what I may suffer from is a physiological tremor (which 100% of people experience) and psychogenic tremors (which are created and perpetuated in one's mind). Psychogenic tremors have no physical origin or development, but are a result of mental focus on tremors which can be brought about for various reasons - for example, hypochondria.
What I have found is that if I catch myself experiencing a tremor and can't stop focusing on it, then it antagonizes the part of my brain that fears tremors. Without knowing it, my body attempts to keep my hand in a fixed position to eliminate the tremor, which causes my body more stress, thus making the tremor worse and more pronounced. What I have learned to do is distract myself when these panic attacks occur. I will find an external source and focus on that for a few moments which will cause my focus to shift from my hands and allow them to relax.
I had a tremor this morning, so I began to tap my fingers together for a brief moment - as soon as I did that, I looked over at my hand and it was completely still. This method allows me to take a mental detour from my anxiety trigger and give my body and mind a minute to collect themselves. Like a child who isn't receiving validation for their bad behavior, they eventually stop because no one is paying attention to them.
I also love the idea about not symptom checking everyday to help eliminate that sense of obsession. So, having said that, I have whole week to enjoy before I have to check for symptoms again. My hope is that with my new sense of insight and control over this matter, within a few weeks, I won't need to check anymore and will began to focus more on my larger sense of anxiety and not just what it is creating.
Again, thank you all for all of your wonderful help and insight!
