I punched a plastic sign thing yesterday a lot and very hard because I was really angry with someone. It was huge straight after I did it and I could only move it a little without awful pain and if I tried closing my hand it felt like the knuckle was stretching? Today it is much less swollen although it is still a bit big. I can make a fist but it hurts loads. It hurts a lot if I touch it at all. It aches quite a bit and I'm having shooting pains in my finger. Do you think it is anything bad?
