There are actually a number of things that i have been doing that are all contributing to the healing of my arms/wrists/hands.
I have a music stand up against a wall. On the music stand I have a firm pillow positioned so that I can lean into the pillow with my fist while keeping my elbow/arm/wrist/fist all in a straight line alignment. There are also subtle ways that I move my fist into the pillow with the tips of my middle knuckles...; anyway I do this with both arms many times a day and it feels really good, healing and beneficial for my condition.
(A friend of mine mentioned that he healed his carpal tunnel by doing pushups, and that is what lead me to pushing my fist into a pillow).
I also use this trigger point roller throughout the day.

I use a back and forth motion combined with a forearm rotation. Forearm Rotation is something that was missing from my piano technique. I use the 26 inch version - this is long enough to do both arms simultaneously. It also feels really good to run your spine across this thing.
I also use a wooden Gua Sha Scraping Tool that I comb up my arm. Wow this feels great!
I also use the Bongers Massage tool on my arms:

I walk every day, and swinging my arms feels really good.
HOT/COLD therapy has helped. Get the arms real hot in the shower and then get them real cold. I go back and forth hot/cold/hot/cold – this will get fluids pumping through your arms to help move out toxins etc....
Rebounding on a trampoline feels really good on the arms – just let the arms completely relax as you bounce up and down.
I place my forearms outstretched on the grass outside or carpeted floor (palms relaxed). Then begin moving forward and back so that the skin of the arm is sticking to the ground, but the arm itself is slipping/sliding beneath the skin – this creates a traction motion that feels really good. I even add a little forearm rotation to this traction move.
I had several treatments with an ART therapist, and I found this therapy helpful. I have been able to self treat myself using some of the movements that the therapist showed me.
www.activerelease.comI also use my elbows to dig into various pressure points that offer relief.
I didn't mean to write the sequel to War And Peace, and I am no doctor, but I felt compelled to share some of what is helping my arms to heal.
P.S. Since I haven't been able to play for three months I have been focusing on ear training exercises using EarMaster Pro Software.
