Steve took the field vision test at Aston (a building connected via hallways and tunnels and ramps to all the other UT-SW-affiliated buildings) and was then wheeled back to Zale for the lumbar puncture.
The LP process was much smoother today. The X-ray helped the doctor (a different one than yesterday) find just the right spot, and they filled four tubes of cerebrospinal fluid. The fluid is clear and almost the same consistency as water.
He's trying right now to fall asleep, which he desperately needs. He must stay flat for at least two hours to help avoid an awful headache. (Poor guy certainly doesn't need another headache!)
We expect to hear later this afternoon if we're going home today.
