Small scooter accident 3 weeks ago hit left side right below breast hard left it sore with huge black bruise. Still sore w/ touch & bending. Normal?

Maybe. Any trouble breathing? If so need eval. pain with overhead reach with left arm, pain with cough/sneeze/laugh all pretty normal with this injury. Can take weeks 6-12 sometimes for this to resolve. At this point moist heat to area a good thing. OTC pain reliever also can be helpful. Best of luck. .
