Alright, I'm gonna come in here and be a bit grumpy. I have no idea why this post is getting so much attention. The responses are actually very surprising to me. If you actually read the post, the person has been twitching for 10 years and is "MOSTLY" convinced they don't have ALS. If you have ALS, you would be the first case in history to present this way. You'd be in medical textbooks. You don't have it. Story over. The fact that you still entertain that you might demonstrates the severity of your health anxiety. The second issue is that the nerve damage is not diagnosed. OP thinks that MAYBE they have something and has not been checked out by a doctor. Guys, am I taking crazy pills? This should be slam dunk "See your doctor and then treat your health anxiety" response.
