I Was Diagnosed As Having Gilbert's Syndrome Two Years Ago.

I was diagnosed as having Gilbert's Syndrome two years ago. On and off during the last several years I have had intermittent itching, sometimes intense, which has grown worse over the last several months. It is most often on my scalp, but sometimes occurs on face, back, arms, groin, etc. A few months ago, I started having a pain in my lower left abdomen that radiates to my back. It is about parallel with my navel, is never intense, and comes and goes during the day. Recently, I went two days without any noticeable pain, but that is rare. It is kind of a dull ache. I have also had headaches, not extremely painful, that also come and go, during the last two months. Does this sound like symptoms that could be caused by Gilbert's ? I have n appointment with a liver/gastroenterologist in two weeks. I have been worried about possible pancreas problems. I take Irbesartan Blood pressure Med, one 81mg aspirin every night, and have had to be on Cleocin antibiotic three times this year for dental work.
