Sensory Integration Disorder is not a problem with her ear tubes, drum etc, but a problem with the brain and ears communicating with each other (that's the intergration part).
There are plenty of kids with this disorder, some have other issues with textures, lights etc. Some have other disabilities too... like Autism.
You can ask ECI in Carrollton to evaluate her for free, because has Sensory issues can delay her learning. If they can't, or she doesn't qualify, they can give you references.
I'm glad you no longer think she's doing it on purpose or being bratty. Remember, she's really too young to make up stuff like that. It's very painful for her, so try to be supportive. Earplugs are cheap and easy. My son wore them at lunch when he went to Elementary school.
You got good advice from the rest. Good luck.
