| Fairly common for bikers. I had exactly the same for years, comes and goes in terms of severity. A related issue for me is on cold days, all my fingers go pure white and I have no feeling at all of clutch or brakes, very dodgy at times. I also lose strength and I found my 748 near impossible to ride as a result (CTS is in my left wrist). There are mods you can get to alleviate the clutch issue, someone who knows more will come along soon.
Mine was always worst at the start of the season if I had not ridden through the winter. I found sitting in the office with a stress ball type gadget and using it regularly alleviated the problem, so a case of building strength and getting your muscle memory used to the position.
If you are on a sports bike, the riding position doesn't help, so consider bar risers. Also, a favourite mistake is bad positioning of your brake and clutch levers, ie having them too high, try to lower them and adjust nearer to the bar if you can, some say they should continue with the angle of your forearm, so you are not putting undue pressure on your wrist.
What do you do all day? I spend some time on a laptop, so it is vital to get your seat height/desk position and stretch to the keyboard all right to take pressure off your wrist, try a soft support pad available from Ryman etc. It all helps.
I avoided the operation and although it was painful at times, I seem to have worked my way through it with physio and stretching and changing some of the above. I now only get it the first few trackdays of the year when the wrist is under a lot of stress with clutch changes - do you use the clutch for changing up the gears? If so, try clutchless changes. You may also be tense on the bike if you are feeling it worst when riding - I'm sure teaching granny here, but it makes a heck of a difference to relax from the head down! Someone told me the vibrating Ducati twin engine didn't help CTS either.
At worst times, when it was so painful I was taking nurofen and could hardly ride the bike, I found severe stretching of the wrist, rubbing it quite violently and using the stress ball was enough to get me through a 20 minute track session or a race.
Look it up on tinternet, there will be loads of stuff on it as it's a common thing.
