So, here's what we know: Tom's EEG and bloodwork came back normal. This means that his fainting episode was not caused by low blood sugar, anemia, or epileptic seizures. This is good news! Chris and I are still feeling a bit uneasy about the whole thing, however. The doctor's office called tonight and agreed that we still need to check a few different areas and this includes an ECG that I need to schedule tomorrow. Luckily, both the EEG and ECG are non-invasive procedures, so our needle-hating kiddo has nothing to worry about.
Additionally, Tom's fantastic kindergarten teacher, Mrs. Anderson, is going to keep an eye on Tom and keep a count of how many "spacing out" episodes he has during a given time during school. Chris and I will also document any time he has migraine symptoms and anything else that seems abnormal. We're hoping that being more diligent about identifying the frequency of his symptoms will either lead us to a diagnosis, or show us that they don't really exhibit as much as we think.
At this point, I feel like we're making the best possible steps. Thomas, meanwhile, went back to school today and is just as sweet and bouncy as ever!
