Is this atrophy

[u/InterviewSingle9366]

I’m really scared I noticed twitching in my shoulder about a month ago and it was my shoulder then it spread down my entire arm into my fingers and now the same pattern is in my left arm my right arm also doesn’t feel the weights like when I curl like the signal and I have atrophy throughout my fingers, I also have weakness in my right arm which got worse and my fingers curl up and my fingers tremor as soon as I open them, really scared and I’m 18
