Amyotrophic Lateral Sclerosis (ALS) is a progressive (KEYWORD), degenerative disease. Let me tell you a couple of things.
1. The tongue twitches happen to me, and it is what I am currently fixated on as well. If I flex my tongue, then relax it, it will twitch (fasciculate for a few seconds). I have only been twitching for almost 3 months now, and I have had serious anxiety during this period.
2. In true ALS Bulbar Palsy (i.e. - the tongue region), by the time tongue fasciculations present there is associated extreme weakness of the tongue muscles. For example, if you stick your tongue out it will deviate (SEVERLY) to the side of weakness. I am a student at Johns Hopkins University, the best medical school in the nation, and have seen 2 patients with ALS - PBP (Mouth Region). Their tongue looks like a shriveled up raisin and they have severely slurred or absent speech. Their voice sounds almost robotic in its tone. So in other words, if you had Tongue "twitching" because of ALS you would be far past the stage of swallowing difficulties and slurred speech; because when twitching occurs in the tongue region these patients are quite ill by that time.
3. You have been twitching for over 3 years which in itself says that there is absolutely NO WAY possible on this earth or in existance for it to be ALS.
Particularly given the fact that you are experiencing tongue fasciculation, which had it been ALS, would be disabled your voice, swallowing, and facial movent functions.
4. You seem to be pretty young anyways to be worried about all of this. I have been to Germany one time, and it seems like an awesome place. Go out and have fun, and totally do not pay attention to your thoughts about ALS, because you DON'T have it.
