I had crazy night sweats when I was at my worst with my anxiety. I would wake up and just feel awful from it. You can have panic attacks in your sleep which you are unaware of. Once I got control of my anxiety the night sweats stopped.
I have never heard of those symptoms relating to anxiety disorder, which i have also.
I think what you are experiencing is psychosomatic feelings in your arms. It's when something is disturbing you mentally, but you have physical side affects. Either way, please get tested to check for sure, and to relieve some of your anxiety
