My doc called it Trigger Finger and it was the third finger on the right hand. It took a year and a half of wearing a splint which you can buy on Amazon. Last August was when I stopped wearing the splint. Still have to be careful it can come back and I don't need another year of a splint. Both hands give me problems from racing scooters and fighting oh and a couple of dances with guys with knives. That damn splint really made writing look like a scribble. Only cortisone shot have had is for the arthritis in shoulders and hip but may have to get shots for wrist and thumb joints. Hope it gets better soon for you.
