Regarding neck pain and/or headache following a spinal tap: he should lie flat for a few days to give himself a chance to recover. Have him follow up with his doc if this doesn't clear up in a few days or gets worse.

I had a spinal tap once that gave me horrendous head and neck pain whenever I stood up. It got to where I was vomiting from pain. I ended up in the ER, and they did a blood patch, and that fixed me right up.
