Not a doctor and thankfully, never fractured the scaphoid...just a former x-ray tech that worked in orthopedic hospital. While things have changed since I zapped people for a living, the scaphoid bone has the reputation for being the hardest bone to heal from a fracture (lousy blood supply). It isn't unusual not to be able to see the fracture--it is a hard bone to x-ray well and the fractures are often hairline.

We had one of the orthopods break his scaphoid bone. Unlike the patients he treated for it, he immediately did the bone scan and he immediately put himself on the electrical stimulator. Even with that he was out for almost 2 months.

I guess, if I were you, I'd be pushing to get a diagnosis and agressive therapy, but I hate sitting idle and am not known for my patience.
