Descent and the others are absolutely right; I wasted a YEAR of my life convinced I had ALS because of Twitching, PERCEIVED weakness in my arms, legs, etc. I saw a total of 3 neurologists on 4 separate occasions and had Electro-conduction studies, strength tests, etc. Everything was normal. But I kept waiting for the day I wouldn't be able to move a leg / arm and I drove myself INSANE. Check out "benign fasciculation syndrome" -- it's exactly what hte name implies (benign). I have fibromyalgia, which is also responsible for twitching, but that's another story, and I'm not saying you have fibro. I've had fasciculations / twitches for 17 years now, and I still manage a home and family, work full time and am here talking to you. Twitching means nothing. With ALS, the twitches present in the end stage of the disease as the muscles waste. So many other things can cause this (Benign Fasciculation Syndrome, Fibromyalgia, severe anxiety, sugar, energy drinks, caffeine, etc.). You DO NOT have ALS... I'd bet any amount of money on it. Hugs to you!
