You ask all the questions you need to and f them if they dont like it. This is a days work for them but it’s life changing for you.
Make a list of your questions. I used to go in with a legal pad, plus I started a 3 ring notebook with dividers and page protectors and an index and I put info on each dr, all his labs, meds, anything else I could get my hands on in there.
That came in really handy the couple of times I had to take him to the ER because he couldn’t stop vomiting .
