My elbow is slightly swollen and bruised. I was boxing and connected with the pad with a straight arm instead of a bent one what's wrong with my elbow?

YOU HAVE A BURSA SACK IN YOUR ELBOW. IT COULD BE BURSITIS DUE TO IRRITATING THE BURSA SACK. MY HUSBAND GOT IT JUST FROM THE WAY HE WAS RESTING HIS ARM ON THE DOOR WHILE DRIVING. THE ELBOW INFLAMED AND WAS IRRITATED FOR A LONG TIME. SOMETHING TO ASK YOUR DOCTOR ABOUT. FOR HIM, TIME, ibuprofen, AND A ELBOW BRACE HELPED AND IT HEALED AFTER QUITE A WHILE.
