Hi,
I understood my heavy arms to be a symptom of TOS.

I also found stretches for my arms to help with the heaviness. I would roll a towel longways, cylinder shape, and place up and down my spinal column and I would extend arms out, like cross shape I guess and then slooooowly raise them, reaching for the ceiling, and brings palms together and then slooooooowly back down. They get easier. I would do these after a hot shower, seemed to work better for me.
My whole arms, every inch hurt. So yeah, unfortunately I know what that is. I don't have that heaviness now. I'm even driving without pillows for props.
I don't think I mentioned to you about the Kinesio tape. They helped with ADLs. You can order it online. You or a friend or health care professional can apply it. Best if used up to 3 days. remove and a day or two later reapply. I wore it for three weeks.
People would ask "R U a burn victim?"
Also, on the taping, if you pull too tight, it can cause muscle spasm. Just to let you know from experience.
