Intestinal Malrotation in an adult

I am 48 yof with pain in left abdomen X-2 weeks. Initial blood work and urinalysis showed mild hematuria, Dr. ordered CT for possible Kidney stones. CT shows Intestinal Malrotation and Dr. is sending me to a Gen. Surgeon. Pain (nagging but not severe) still persists with constant mild nausea and heart burn and now I have a bulge in the LUQ, I have also had chronic constipation most of my life. My question is should I be going to a surgeon first and if so what should I expect, ask, etc. All I can find on the internet is that the condition is rare and the Ladd's procedure is normally done. I had a c-section in 1980 and complete hysterectomy in 1985, diagnosed with duodenal ulcer in 86 and laporoscopic surgery in 2001 for LLQ pain where he released my bladder which helped the pain back then.  I am somewhat confused as to why this wasn't found and treated during one of those procedures. For informational purposes I also have hemochromatosis, a total thyroidectomy in 06 for a multinodular goiter with papillary cancer and breast reduction in 2000 which found atypia cells. I prefer to be an informed patient and would appreciate any help you can give.
