My finger hurts cause I boxed a friend

So I boxed my friend for a 30second match and I gues I punche him wrong cause now my thumb has been hurting for 3 days every time I fold it it hurts . Should I just put ice on it or what?

Maybe you should get an x ray? You might have a chipped bone or something. I had something similar happen to me before :)

Fingers have a lot of bones and tendons. I am a boxer and even with gloves and wraps, sometimes I jam my fingers. I can take a while to stop hurting. Personally, ice doesn't seem to help me, time is the only cure. If you broke a finger, you would know I think. When you jam your finger or over stretch the tendon, it can be quite painful.
