smithylab,When I first started to experience the trigger finger symptoms in both middle fingers, which was probably a year or more after my twitching started (and was at a time when my twitching was at a low point, actually, which is why I don't suspect them to be related), I went to my primary care doctor. It was he that noticed some subtle signs of osteoarthritis in the joints of my pinky fingers (small Heberden's nodes), unrelated to the trigger finger issues. He said I was "a little on the young side" to be showing such signs of osteoarthritis, but not enough to concern him. That was 2 years ago. I'm now 48. Occasionally, those pinky joints are sore to the touch, but in general, the osteo stuff is not bad for me (yet). For you, at 30, I'd say regular arthritis should not be a concern at all. The trigger finger problems were sufficient enough for him to justify referring me (at my request) to a hand specialist. The specialist performed the cortisone injections (not fun, esp. for a squeamish person like me), and it took a few weeks for things to improve. In fact, they got worse before better, but they definitely did get much better. At it's worst, I could barely curl my middle fingers inward more than half-way. And if I curled them in further that that, they'd hurt like a SOB and be difficult to straighten back out. Now, I'd say the fingers are 90-95% recovered. As for the cause, my doctor felt it was just something that happened; nothing related to anything autoimmune, neurological, or anything else. Maybe calcium deposits. But in short, "just one of those things that some people get." I lift weights at the gym, and it could have been irritation of the tendon from the pressure of the weights; can't say for sure.The one caution I got from my specialist regarding the injection : he said they will only perform them twice at most per finger, because any more than that tends to weaken the tendon. So, if you are bothered enough by this to go the injection route, you have two chances -- after that, the next treatment is surgery to open the tendon sheath. Sounds scary, but it's supposedly very successful in permanently resolving the issue.You wrote: "My luck is that I would flip someone off ( which would be easy where I live,) and get my finger stuck in that position forever!"My mother used to say that about crossing my eyes. Luckily I escaped that fate. But who knows, maybe eye-crossing (or bird-flipping) causes widespread fasciculations....or trigger finger....
