New symptoms

I have noticed that my right arm is becoming progressively weak. It kind of aches a little and it feels so heavy it feels like the weight is pulling down from my shoulder blade and it’s spreading down past the elbow now. It hurts to continue using my right hand and I can see and feel the difference between the two. There’s definitely muscle wastage as it’s much thinner. I feel it pulling in my neck now too. Is there anyone who can share their similar story with me? I really appreciate your time.

I don’t have any advice for you I’m afraid but I was interested to see your post as this is how my right arm has been since around July. I’m being sent to see a neurologist (which is how I ended up on this forum). Have you been to the gp?
