@megustapunkrock: It's been awhile since your original post so hopefully this message finds you well. I've become sort of an expert on ALS having gone through a terrible scare myself that lasted almost a full year and involved multiple visits to different neurologists. So let me put your mind to rest -- you do not have ALS! There are several very strong reasons why.
1. You've been experiencing tongue symptoms for more than a year. As MSNik noted, if you had ALS, other symptoms would have developed by now. ALS is a fast moving disease. More symptoms would develop that are unmistakable. Since you don't have other symptoms, I'm 100% confident you do not have ALS. I was told this by one of the leading experts on ALS in the world -- Dr. Miller of the Forbes Norris ALS Research Center in San Francisco. He literally wrote the book on diagnosing ALS (go ahead, Google it if you don't believe me
2. ALS overwhelming occurs in people over the age of 60. The odds of getting it at 28 are extremely extremely rare.
3. When I stick out my tongue, it shakes like crazy. In fact, if I look at my tongue in the mirror, it's always moving. Those movements are involuntary and perfectly normal. One frustrating part of health anxiety is that you become hyperaware of what's going on in your body and often mistake perfectly normal sensations for something bad.
4. My muscles twitch all the time. All over my body. My calves twitch. My forearms twitch. My neck muscles twitch. The twitching started in my mid-20s. It happens all the time. I learned to ignore them. There is a condition called BFS (benign fasciculation syndrome) that inflicts many people. It's called BENIGN because it's totally harmless. If you are interested in learning more, there is a whole forum devoted to it with hundreds of posts from people who suffer from BFS and misinterpreted their symptoms as ALS.
@Cerval1: Arm pains are not a symptom of ALS. ALS is a non-sensory disease -- meaning that you don't get pain from it. It also progresses asymmetrically meaning that symptoms would start on one side -- not both sides. So your symptoms don't sound like ALS at all.
To both of you, if you are concerned, please visit a doctor. But do yourself a favor. TRUST your doctor. Trust that they know what they're doing. Trust that they know more about medicine than you do after 30 mins of searching on the web.
Google is not a substitute for an informed medical opinion and Googling your symptoms does not make you a doctor. There is a reason why they went to medical school and spent many years in residency.
So do yourself a favor. Take a deep breathe. Now say aloud with me: "I do not have ALS." Say it again and again until it sinks in. Because I promise you, as soon and you stop worrying, your symptoms will fade away. It my take awhile, but one day you'll notice that they're gone. That's what happened to me. I only wish I had not wasted a year of my life worrying about ALS before I finally accepted that there was nothing wrong with me.
