What can I do for chronic tendonitis in my wrists?

I developed tendonitis in both wrists working as a teamster in a warehouse last summer. Most of the time it’s fine, but I work in an office and the typing sometimes upsets it. I also ride my bicycle everywhere rather than driving, and I get pain shooting down my wrists when I ride. I have custom splints but they are too stiff to wear when typing or riding. I prefer not to take ibuprofin or other painkillers any more often than is absolutely necessary.

I plan to see my doctor about this sometime in the next couple of months, but if anyone has any short-term solutions or suggestions, I’d appreciate it. Thanks!
