Over the past year or so I have been getting tremors in my fingers whenever I go to do something, these tremors are for the most part always present but range in severity, it seems the more I exert myself physically, the worse they become. I heard someone mention an "intention tremor" that kind of helps me describe the tremor itself, it only happens when I go to do something with my fingers that it does it. For example if I try to put my finger very close to an object without touching it, it will shake. Right now if I slowly reach for a specific key on my keyboard with one finger it will shake. On most severe occasions, say after i've been lifting weights or doing pushups or working in construction all day, lifting a fork to my mouth will cause a tremor in my hand. I've been researching on the internet and found that there are a number of neurological disorders that can be related to this and quite frankly, it is starting to scare me, anything from huntington's disease to parkinsons disease, the reason this scares me the most is that i'm only 19 years old, so these could just be the start of something greater. Please if someone could tell me what this could be and if it is as serious as I fear it might be I would greatly appreciate it.
