Oh goodness gracious, go to a rheumy now!!! <faints>
LOL, seriously, yes, I think you need to see a rheumatologist. With PBC in your genes you might want to get a Celiac blood panel too, if you haven't already, they're usually given by a gastroenterologist.
Not to add yet another doc/disease to your list! I come from a multi-autoimmune family too, so I know the drill. (juvenile arthritis, RA, Celiac Disease, ulcerative Colitis, vitiligo, autoimmune hypothyroid, MS, Crohn's Disease . . . and the list goes on
