It figures that Yours Truly would be diagnosed with something called Trigger Finger.
Or, in my case, Trigger Thumb.
About 10 days ago I started to have this very uncomfortable situation in which every time I bent my left thumb, or then straightened it, there was a popping sensation. It's worse in the morning, gets better, then gets bad again at night.
Here's the definition by Wikipedia: "Trigger finger, trigger thumb, or trigger digit, is a common disorder of later adulthood characterized by catching, snapping or locking of the involved finger flexor tendon, associated with dysfunction and pain. A disparity in size between the flexor tendon and the surrounding retinacular pulley system, most commonly at the level of the first annular (A1) pulley, results in difficulty flexing or extending the finger and the “triggering” phenomenon. The label of trigger finger is used because when the finger unlocks, it pops back suddenly, as if releasing a trigger on a gun."
Got that? The simple explanation is that a tendon nodule in my thumb has become inflamed and then every time I try to bend my thumb, the nodule "catches" on the sheath. Ouch.
I can imagine all of you squirming in your chairs now. Or maybe some of you have experienced this. Note that it says "later adulthood." Double Ouch.
Causes are unknown, but apparently there is plenty of anectodal evidence showing that manual repetitive stressful manual motion as a cause. Which doesn't surprise me at all. I know that some of you were suggesting it was from texting, but I rarely text. I do know that I'm on the computer a good 8 hours of the day. At least it's not arthiritis, which I feared.
All this is the reason why I'm not writing much lately. I'll be taking it easy until this eases up, and taking anti-inflammatory meds.
Dont' forget the contest is coming up again, Entry #2, sometime tomorrow.
