Hi,
You certainly have had your share of troubles. Bless your heart.
I have tried a few things for arms that may interest you. Kinesio Tape. Not a miracle but it does help with ADLs.

The LED and infrared lights gave me great relief. They are becoming more and more recognized. Chiropractors and physical therapists use them, massage therapists. Check around in your area for an opportunity to try them. Mine are pricey but I think they are worth it.

The Miracle Ball set helped me with tender points and trigger points too.

Also a Theracane:

Oh. And keeping my arms fleece warm helps them. Looks stupid in the summertime but...
probably many more things over the years.
I do hope you find some relief. I know it's not easy.
Here's some extra hugs for you. ((()))
