EEG Results OK

On the surface, that's good news, but if it's your mom who has been sick for the past 3 1/2 months, with no accurate diagnosis in sight, then it's not so good. I thought for sure it was a nerve issue because is complaining of cold legs, but I'm not sure an EEG will show any nerve damage. We're starting to run out of hope here. I don't know what else to do or how to feel.
