Is this normal???

My son is 5 years old and has always been a healthy little boy. Recently in February he came down with some neurological symptoms such as double vision, drooped facial muscles, slurred speech and etc.  he got better over a week or so (he was not in my care at the time o  ...  [More]    f onset symptoms) but when I got him an appointment they found a lesion in his brainstem and admitted with the diagnosis of brainstem encephelitis. Almost a month later we had another MRI done after treating this with seroids and he now has 3 additional lesions instead of the 1 to start with.  I have been very iffy on the Neurologist who has been treating him and we are getting second opinions but my son is now having balance issues and sleep issues along with everything else.  Has anyone ever heard of it getting much worse before it gets better? the original scan differential diagnosis also included brainstem glioma.  I feel helpless right now not being able to do anything but keep my son safe, he is my life and I want to make sure nothing happens to him :o(
