Pulled something

Last night I was having a bonfire and my brother was setting off fire works. Well he thru a couple used fire work tubes in the fire. I was moving everything around to get the fire to die down and go out and there must have been some powder left on one of them cuz sparks started flying and of course I jump up out of my seat real fast and take off running pulling my round ligaments and now my belly is so sore. Little lady's still moving around so I know she's fine.
