Max,
I feel your pain literally. I had mine flare up in February of 2005, I went for Tens, Physio the whole deal. Nothing worked, because mine was not really for related i had to pay for my surgery privately or wait three years., Pleas read the following quotes very carefully "where I am certain that at least a good portion of your injury could be caused by work, especially work in the cold" you might want to consider filing a Compensation Claim in the province you work in. Work Safe BC and the Alberta Equivalent fast track these type of injuries.
I was not so lucky and had to pay for mine personally but it was money well spent. I had the first surgery done June 1st and the second done the last day in June. mid August I rode to Denver, finished the Iron Butt Rally and rode home no problems.
My carpal tunnel finally really flared up in 2005. How bad was it well I couldn't hold up a newspaper for example.It was as best we can figure out a combination of things
1) bad ergos on a BMW 1150 GS until I fitted the Ricky Bars
2) worse ergo on a Honda Goldwing. It needed all sorts of modifications
3) ill fitting Held gloves that put pressure on my wrist. I had worn Helds for years and then they sent their manufacturing overseas and for me the fit was gone.
4) 30 years of skiing 60 + days a year and being too tall for the longest ski poles starting wrist issues for me in my mid teens
Vancouver has a lot of good hand surgeons my surgeries were done by Arko Demianczuk (he used to ride sport bikes and understand what we do)

The major decision you will have to make post surgery is what kind of a motorcycle you will be riding.
Sport Bike Ergonomics will no longer be your friend. You may be able to get some more years out of riding with Heli-bars. (I have been the the plant and know the owner) but quite seriously if you plan to keep riding you will likely be moving to a dual sport.
It is nit just buying V-strom and ri=ding off the lot with your face down.
To look after your wrists you may end up spending hours getting the right set of handle bars and bar riders set up for yourself, going for a custom seat , etc,etc. Some sport tourers have enough after market ergonomic farckles that you will be able to fix your riding position. The FJR seems to work for a lot of riders.
Good Luck
