Certainly looks like an odd hand to me. What's that lump on your wrist?
Based on the type of move you injured it on, certainly fits with an FCU sprain. No tenderness deep in that side of your wrist? the other structure lying just proximal and deep in your wrist is TFC (triangular fibrocartilage complex). Can be injured in forced ulnar deviation, but doesn't sound like thats the problem. My money is on FCU sprain still though. Usual caveats apply, take it easy for a little while.
Is the pain directly over the X?
any tenderness if you press into the ulnar side of your wrist just above the lump? (Lump mentioned looks like your ulnar styloid).
Any grinding/clicking? Any tenderness over your FCU tendon (find it by feeling just proximal to X in your wrist. Its the ulnar most tendon in your wrist).
Just noticed it's where my wrist rests when I'm using my mouse. That's probably not helping.

Added benefit of stopping people hotdesking on my desk due to inability to fear of the weird mouse.
