I only bike 6 miles a day but I have developed carpel tunnel, or so my doctor says. My physical therapist thinks otherwise. I have pain in the joints of my finters and inbetween my fingers I get sharp little pains, not to sharp but bothersome. I'm not sure if biking bothers it though. I am wearing biking gloves and my commute is not bumpy at all.

Anywho I am thinking of rollerblading for a while in the summer to see if it helps alleveate my hands. Does anyone else switch from biking to a seperate form of transportation to work? Besides recumbents, I just don't have the money for one.

Nope, but i saw some guy the other day rollerblading using ski poles to push him along for extra speed, that looked fun.

I have been diagnosed with CTS also. Mine comes from years of lifting weights, riding bikes, and using keyboards. I do not think road buzz is the culprit. Bike fit likely is, however. What's your bar height like? I spent years riding with the bar a lot lower than the saddle, which caused me to put pressure on my hands and didn't help. So, once diagnosed with CTS, what did I do?

1) I raised the bar. My bar is now at saddle height. Much better.
2) I bought Spenco Ironman gloves. Their palm is designed with a channel to eliminate pressure on the nerves in your palm. They help.
3) I wear braces when I sleep. They prevent me from bending my hands over.

As for your rollerblading idea, I'm sure it's fine. But there are ways of dealing with CTS.

I assume you are riding a flat-bar bike. How are your brake levers oriented on the handlebars? Are your wrists cocked at an angle when you ride, or are they straight? The ignorance of people who assemble bikes in LBSs is such that they almost never check the angle of the pods from the factory, which is horizontal; they should be between 30 and 45 degrees angle.

How much weight are you placing on your hands when you ride? Are your elbows locked? If so, you have issues back at the seat.
