I took Iyyar to the doctor today. He (doctor) said that his (Iyyar's) muscle weakness is not what he would expect in a kid with [horrible disease we talked about last night], which is reassuring. However, if he's weaker/less coordinated than he used to be, that's concerning, and so we did a blood test, which will be back on Friday. "He doesn't look to me like a kid with [horrible disease], but I've been wrong before, and what you're telling me is something we need to follow up on." So.
My hopeful idea, as of half an hour ago--could this (wobbly legs, bumping into things, not being able to get up without hands) just be a post-tonsillectomy growth spurt? Growth hormone is secreted during deep sleep, of which Iyyar has had practically none for probably months. He's got his appetite back and is doing some serious eating these days. Surely he's doing some growing. Could that be it? Maybe?
