I walk like a duck!! help!?

okay. so i basically walk like a duck. my feet go out... farrr out when i walk/run. it's sooo embaressing. i hate it when people walk behind me. when i was real little my mom took me to a hip/knee specialist & have this weird hereditary thing that i got from my dad (cuz he walks the same way, but only one foot goes out) that makes your feet go out. i've tried to just turn my feet inward when i walk, but it hurts my knees like crazy!! & i can't even do squats while working out, b/c my feet always turn outward, & they're supposed to be inward. & my knees always hurt when i run, it's like a painful jolt going through it.
any suggestions on how to permanetly make my feet turn the normal way. & how to get rid of my knee pain?
it would help a lot !!
thanks :]
