I wrote this once before, but my browser decided to crash when I hit send. Ugh.
Having worked in Industrial Safety for several years, we had training in various things. One year, at a seminar, I took a session on industrial related diseases. Towards the end of the session, the physician giving the class talked generally about things.
He said if a patient presents with one symptom, they listen, two, they consider, and three or more they stop listening. I'm not suggesting they don't provide proper care, but when too many unrelated symptoms present, they rely on testing. If someone complains of the bottom of their left toe being number, and numbness near the right hip, and a patch in the middle of their forehead being numb, they probably aren't related. But if someone says half their body goes numb, or half their face, it makes more sense from anatomy.
I had an undiagnosed seizures for 15+ years. My symptoms worsened, but still the doctor refused to listen, he actually threw me out of his office, I went to another neurologist, he ordered a 24 hour monitor, and from the moment I had it on, it was showing characteristic spiking (Temporal Lobe Epilepsy). I was medicated and 15+ years of symptoms disappeared.
If you go to another doctor, try to avoid having your records transferred, the previous doctor may have voiced his opinion in them. If the new doctor wants the test results, he/she should be able to get them directly from the place that did the tests.
Hang in there, I've been through it before. What, exactly, causes your concern about seizures?
