Fall cause Ptosis and weakness of legs ?

my 9.5 month old daughter took a fall to the head from her portable high chair propped up on the table. She fell on her left side of her forehead, but I noticed later that her right eye is drooping, just a millimeter. No sig. damage according to Opthamologist. Eyesight won't be affected. But, I noticed that she is not walking w/ my help like she used to. Maybe her legs are not as strong?? Getting me worried.... She is starting to cruise, but she won't walk w/ my help anymore, nor stand up against the portable tub anymore. Does it sound like she has had some neurological damage??? I'm very worried about her. Also, will the drooping persist or remain where it's at?
