Suspecting Bile Acid Malabsorption (BAM) with oily stools. Anyone else get scapular/sternum pain or hives?

Hey everyone,
I’m looking for some insights or shared experiences from anyone dealing with fat malabsorption.
For a while now, I’ve been dealing with chronic fat malabsorption—my stools are consistently oily and greasy. Because of this, I strongly suspect I might have Bile Acid Malabsorption (BAM), though I'm still looking into it.
I'm trying to connect some dots before my next doctor's appointment, and I wanted to ask if any of you who have experienced these same symptoms also suffer from:
Pain behind the sternum and in the scapular area: I get these distinct pains right behind my breastbone and in my upper back/shoulder blade region.
Hives (Urticaria): I've also been experiencing random outbreaks of hives.
Has anyone else noticed a link between fat malabsorption/BAM and gallbladder-like referred pain (scapular/sternum) or skin issues like urticaria?
Would love to hear your thoughts or if anyone has gone through something similar. Thanks in advance!
