Could it be triggerpoints causing some of those feelings?

When my sx show up forearms are the usual place, aside from the achy neck/shoulders stuff.

My forearms are lumpy & bumpy when I rub my hand slowly over the muscles, top is worse- knotty /ropey the PTs called them.

A little bit all the time but worse when I use them repetitively and when neck gets tight.

Been fixing my puter all day today so arms are starting to complain.
means extra home therapy time tomorrow.
