Hello,
I'm here wanting to ask a question about some sensations in my left arm. My upper left arm began hurting about 4 months ago, just an ache, throb type pain. I recently have started having visible muscle twitching in the upper left arm as well, with some small twitches in the back of my left shoulder. I have to work harder to have good motor skills in my left hand. My arm feels weak, but I don't think I've technically lost any strength.
Does any of this sound like it could be early als?
