The poor boy had to undergo a barrage of tests - from blood and urine tests, to a spinal tap, to an X-ray, CT scan, MRI, short and long EEG, and an ultrasound. That's more tests than I have had done in my entire life.
I am feeling a bit nervous to have him home because I don't want the same thing to happen again. But, I guess that's one of the things you have to get used to as a parent. The worrying never ends!
Thank you to everyone for your support. I really really hope this is the last time Evan sees the inside of a hospital for a long, long time.
