Trigger Finger

There is so much good stuff going on, I don't know why it so often ends up being the bad stuff that finally motivates me to write on my blog.
Good stuff is that I'm feeling like I'm making progress with my swimming. I'm getting more mileage in, both biking and running. Training is going pretty well.
The bad thing is trigger finger. I have a self-diagnosed case of trigger finger in the pinkie of my left hand. I haven't seen a doctor about it yet, but it's a pretty obvious thing to diagnose.
Trigger finger occurs when a tendon that flexes one of your fingers gets a nodule of cartilage stuck on it, so that it can no longer easily slide through the sheath of tendons that hold it in place as you flex and extend the finger.
The finger can get stuck in a curled position, like it was wrapped around a trigger, and make a slight pop or snap as you extend the finger and the nodule moves past the tendons obstructing it.
So now I am waking up in the morning with my pinkie curled over and locked, and it's getting harder and harder, and more and more painful, to extend it out normally.
This condition is way more common in diabetics, and especially in those who have had diabetes for a long time. Treatments include rest, cortisone injections, and surgery.
I'm going to start by resting it. I'll start by splinting the finger in an extended position. The hope is that once the tendons aren't rubbing against each other all the time, the nodule will break up and go away.
I suspect that leaning on my hands while riding may have started the problem, so I'll get a new pair of biking gloves with more padding. And I'll try to spare the pinkie while I use the handlebars.
However, often this condition eventually strikes more fingers once it has hit one.
