t need to use that hand for playing my
trumpet. Well, soon after, my knuckle got really
sore and red, the bit of swelling went down over time. I could still move my hand just fine though, so I thought it was okay. Now though, I thought it was all good, but when I went to playfully punch a friend in the arm, it flared up in pain again. Have I fractured or torn anything? I'm quite worried about it. Thanks!
