Rash.....

So I started itching and got this rash.. I called the obgyn and spoke to the nurse she said they Dont do skin. Which seems so stupid considering I know other pregnant woman have had to go through the same thing. Anyway I went in and insisted they looked at my stomach and skin and she said it's allergies I told her no it has to be pupps and she said no pupps only stays in abdominal area...anyway I go to the ER and doctor says I have pupps mind you I'm only 25 weeks. I MADE AN appointment with the obgyn doctor and they sent me to take blood work to see if its pupps or cholestasis. Has anyone had experience with cholestasis. ? She said you can't tell between the two only by getting blood work will you know . how far along can I switch doctors??

In very frustrated.. If it ends up being cholestasis I would be pisses considering the nurse could of cause issues in this pregnancy.
