Thanks...He said it was "probably a small tear," he actually couldn't see anything (used a contact to look) except for fluid at the top, and so thought that must be the reason. He didn't do ultrasound today, but did OCT and everything looked okay. The bottom of my eye was quite dark, so I assume that's from the fluid.

He said to keep my head tilted partway down (reading position) as much as possible, but that being upright and sleeping on my side was okay. Now I just need to find a way to keep myself from turning onto my back during my sleep!
