OK, we're back to plain ol' osteoarthritis, with a side-order of tennis elbow.
The occupational medicine doc asked a third-party physical therapist to review my condition, and he concluded that I am pretty much over the deQuervain's, but my thumb joints are definitely arthritic. The tennis elbow is just an unwelcome bonus (and he bruised me up pretty bad doing the initial treatment).
It sucks to hear that I've probably got a permanent condition -- newest doc wants to look at the bone scan and blood work before saying anything for certain. I'll probably check back into counseling once I've got word, just to help adjust the ol' brain. :D
Oh, and I'll have to repeat until I believe, "Opening an L&I claim does not make me a failure." Darn early programming about only losers getting help from the state...
