(Could have sworn I posted this last night, but apparently I just saved it. *shrug*)
Tendinitis.
I’m to rest it. Which will be no easy feat, considering it’s my left hand. And I’m left-handed.
I’m on an anti-inflammatory patch. Ok, actually, the patch is on me. And wrapped with an ace bandage, but I can use the brace my stepmom gave me if it works. Which it does sometimes, but then I end up yanking it off because it drives me crazy. So far, I’ve successfully left the ace wrap on all day. I might try the brace tomorrow, now that I know it’s not doing more harm than good.
The best part? No dishes! Doctor’s orders. My children and The Boyfriend will have to cater to my every whim. Gee, darn. But I’m not restricted from computer use, so that’s a plus. Hehe…
Oh, and I have to go back in a month.
Completely unrelated, but still important… if a particular someone out there is reading this and that certain someone rarely spells out his whole name when signing emails, after I left the doctor’s office, I turned on the radio to hear a certain song by the Goo Goo Dolls. And no, it was not immediately followed by Tal Bachman. 
And that is all for now.
I knew it! When you were describing your symptoms, I was like that sounds familiar, but I didn’t want to get your hopes… down.
I had the same thing. I lost all use of my right (dominant) hand for 3 months. Man, that sucked.
Good luck to you.
