We have almost the same problem. I enjoy the same activities as you and deal with a similar injury. It sounds like you have a scaphoid fracture. It is difficult to detect on x rays because of the lack of blood flow to the bone. Also, the lack of blood flow makes healing difficult and has the risk of forming a "Non Union". This can cause arthritis and a build up of scar tissue. My wrist is of the "non union" sort. I exercise 6 or 7 days per week and have never missed a workout due to pain. The key is to learn to work around the injury. I have found that what works best for me is to consciously lock my wrist prior to any lift and only allow flexion at the elbow and not the wrist. Bench Pressing is tricky. Lighter weight dumbells or bi lateral machines seem to work the best for me. The smith machine also is a good fit because you can focus on pressing the weight and not having to stabilize the bar. Basically... where there is a will there is a way if a guy with no legs can run a race in the Olympics... then you can lift weights
