Rheumy's can be difficult at times, which is to bad. It takes so much out of us to travel to see them and then have them treat us like we're 5. I know with me I started having symptoms of lupus in my late teens like age 17. When I was 22 I had my first positive ANA test and loads of symptoms. It was mentioned by my internal med doc that I might have lupus.
Nothing was done about that and they doctors continued to go back and forth on whether I had it or not. Fast forward 13 years and finally I hear the words "YES, YOU HAVE LUPUS". Man of man did I wait a long time for those words, and they treatment was even more important to me. Heck they said I had RA before I had lupus officially.
I wouldn't get to upset over this rude jerk, so ahead and get another opinion. Sounds like it runs heavy in you family history. I'd get checked again, but try to remember sometimes you'll go through a few Doctors before you find the right one.
Wishing you the best and will look for updates from you. I hope they get it figured out real soon and you start feeling better ASAP.
