Hi Mark,

Thank you for your help.

It does feel exactly like the first time, except for the added neck pain and some trouble sleeping (didn't have either symptom the first time around). It just feels like there is a lot of pressure in my head, and like my scalp is on fire.

I will wait until the CAT scan results in two weeks to take this up with my doctor. Do you happen to know the procedure for CAT scan results? I am wondering if they do look at them earlier, and see something is up, if they would contact my doctor sooner, etc. than the two weeks?

It's pretty discouraging to think that, just when I was feeling better about 5 months of PCS, I may have given it to myself again and might spend the next several months in pain. But I'd rather play it safe and get better.

Thank you again for your help.
