Smacking ears and no diagnoses

Sabrina

My daughter is almost 9 months and for the past 2 months she's been smacking her ears hard and yelling (like they are bothering her) I haven't found a pattern. She just does it at random times.

I have taken her to a a pediatrician multiple times. They say her ears look fine but I'm just having a hard time accepting that. I feel like there's something going on...

Not really sure what to do now since the pediatrician claims her ears are fine. Opinions?
