I was just out playing hockey with my neighboor, and half way through it i noticed that the middle of all my fingers (besides thumb) on my right hand. When i try to bend them, it feels like a build up in the middle of my fingers, and they wont completely bend. I tried putting them under warm water, that didnt work. Anyways, my mom says they are swollen. Thats all the detail i can give, if you have any idea what this is, tell me please.
