I am not sure I understand the buzzing symptom I hear a lot in this forum. Terminology can be tricky is this illness, at least in my experience!! I try to explain how I feel to others and a lot of time I just say "odd sensation", because everything just seems so odd and foreign to me. Like my arms, they feel like they are not connected to my body sometimes. I wake up and they feel mildly asleep, not numb, buzzing, just strangely awkward and heavy. I have had a hard time with my arms because I used to sleep with one under my pillow or above my head. I certainly cannot do that anymore, so I have started bending them at the elbows and placing them on my chest. I have the same problem with the dishes too, and like you said I now also do a few at a time and don't push it, or do it daily. I have moments (3-4 during the past two months) where it has been extremely difficult to raise my neck up from a laying position, terrible pain. Not sure if that is a spasm, more like a sharp jabbing. My shoulders def. have muscle twitches, along with many other muscles in my body (side, arms, abs, calves, neck, back, lower jaw, etc. etc.) Not sure if this helps, but it is always good to have support and know people are going through the same health issues. I hope you have a good day today
