They can't find what's wrong through normal tests, so they'd have to crack open her skull and dig around directly inside her brain to find the actual problem. Another issue besides potential side effects like going deaf is that the recovery period would likely be pretty long and she has no one to stay with. I think she's worried that the brain surgery has a high chance of leaving her permanently fucked up, so she's trying to accomplish as much as she can before she finally gets it one day so she has no regrets.
