i understand not being able to go to PT....
if i had known then what i know now, i wouldn't have had to have gone most likely.
a lot of what i wrote, i learned in PT; some was by my own trial and often error.
you are correct to not overdo the other hand.
i didn't realize that at first; i had always been healthy and figured that the left wrist was just a fluke, so i did everything one handed including typing and steering while driving my car - that caused me to develop the same tendinitis in my right wrist within about a month of simple overuse.
but that wrist never got nearly as bad because i kept it out of the brace and had by then learned the other tricks, so i was able to treat that one on my own initially when it was newly inflamed, and have managed it mostly ok for almost the last 10 years (wow, i can't believe its been that long).
i've also been meaning to get voice recognition software,
i almost did when i hurt the outer-side of my left wrist,
but i never found the time.....that would probably help all of us
with wrist issues.
hope you find some relief soon, be careful with your hands, and if you have any specific questions, feel free to ask, but try not to type too much
