The itch

I posted about a week ago about being very itchy at night and a lot of people suggested I get tested for Cholestasis.

I did get tested and should get my results by Friday.

I thought I didn't have it because I wasn't at all itchy last night. but now, I woke up about 30min ago and I cant go back to sleep because the itching.

my question is: does the itching from cholestasis come and go?
