I Stepped Off The Elliptical And The Moving Pedal Clipped

I stepped off the elliptical and the moving pedal clipped my lower leg, above my ankle. thankfully not my ankle. I finished my workout with no pain but as the day has gone on it has swollen up to a hard golf ball and hurts! no affecting my walking. I put an ice pack on. anything else?? is it a soft tissue injury or bone bruise. :9
