Hi I am 20 yrs old I’m afraid that I have als. It all started because I had a twitch in my face and of course the hypochondriac I am I went to doctor google. And of course it said I had als. I freaked out for like 2 days. Then I started to get twitching all over my body. Can happen anywhere from my feet to an arm to my shoulder to a calf, to a hip. There’s also dents in my biceps on the side of them. In my arms.
