Hi Trish,
glad to hear you are feeling a bit stronger and that your incision is healing well. Hopefully your other post-surgical issues will improve bit by bit as well. The double vision sounds awful, though! If it doesn't improve soon, I hope you'll press your opthalmologist for help with the issue, or find a new opthalmologist!
I'm actually wondering, though, whether double vision is a neurological issue or a opthalmologic issue. I don't remember experiencing double vision per se (but my memories from my '89 surgery are pretty fuzzy, as far as the hospital stay goes)--but I do remember that my eyes were moving independently of one another the first few days and it was really hard to look at anything,, much less focus. If something similar is going on with you, maybe a neurologist (or your neurosurgeon) would be an appropriate source of advice?
It's great that things worked out with your in-laws, and how exciting that Cali is walking!
Carrie
