I have jammed two things before my thumb and right big toe. On my finger I was jumping a wood fence with my 15 year old cousin and I fell hard on my thumb. He takes a look and thinks its jammed. He takes out his phone to search up symptoms and I had them all. He tells me" oh ****. I think it's jammed. The only way is to take it back out by pulling it back out "and I'm not going to lie when it was still jammed and when he unjammed it it felt like a ******* bullet had went through it. And I say" son of a b**** dude, just hurry up" he pulls it back out and me and him heard 2-3 loud pops and it came out. 3 months it was sore.
when my fingers get jammed i get someone to pull it sharply it helps it gets unjammed but hurts very bad 4 a day or 2...
Hope it feels better now , not much they can do with fingers ,kind of wrap them, like with toes or strap them together,if you can get to a clinic it would make you feel better but perhaps if you cant wrap it up frimly and let it heal.
