Hello, I recently began to notice my middle finger twitching sporadically on and off throughout the day. It suddenly just jerks from side to side and on the top part of my hand i can see the skin moving. On top of that, I feel like that hand is weaker than normal and things feel heavier, however it is more from a pain that i feel in my wrist than from actually not having the strength. Everytime i try and lift something or open a door, turn a key, etc I feel a pain in what feels like the tendons of that hand at my wrist. I am very concerned about the possibility of ALS because of the twitching and the pain, so please tell me if this sounds at all like it could possibly be the very early stages of ALS, and if not please tell me why you feel that it is not. Thank you very much for your time and help.
