There is a movie abouta women who sees a murder on a bridge and then her phone rings and the guy chases after her and throws her off of the bridge and as she falls she hits her head. Then later she is found and put into the hospital and she doesnt recongnize her family and friends faces and the doctor would leave and come back and have a different face everytime and thats how it was with everyone. any ideas!?!

Sounds like Faces In The Crowd (http://www.imdb.com/title/tt1536410/).
