hit a curb :(

i was trying to be a hot shot backing out of the parking lot and get out swiftly and while i was doing so i hit a curb i didnt know was behind me. i hit it on the passenger side both wheels went over, and im not sure what damage i could have done. when i turn sharp to the right i hear a scratchy noise. when i go over other bumps i hear a clanky sound for a second or so. its not like a squeak. any help would be great! thanks
