It's been a while--so a quick update. I've not seen a Doc yet, have not used wrist braces, nor has my setup changed since last posting. Still have my slab of cardboard under the HHKB and the location/position has not changed either.
What has helped me the most in combating discomfort is simply distancing myself away from work AND gaming. Stopped putting in overtime hours (unpaid overtime) and also stopped taking work home. Also I've stopped my daily gaming sessions and cut them back to at most 3 or 4 times a week. As of now my arms, wrists, fingers, and hands are much improved from when I first made this post. I still make conscience efforts to "monitor myself" and if I exceed a certain time limit sitting and working, I'll make myself get up and take AT LEAST a 15 minute break.
Earlier this year, I believe I crossed the threshold of no return with the carpal issues--they seem to be here to stay. By no means am I pain/discomfort free but the symptoms are far easier to manage than previously. Now I just cope and deal with discomfort when it arises as I know what to expect now. Hitting a fat golf shot will light my wrists up occasionally, but that happens to all golfers carpal or not. It has also been a good while since my wrists had that "sustained burn" from the inside thank goodness.
