Hi...I posted a message about a month ago and i am still having problems.  My problem is pain in the left side...sometimes in the upper-mid back, sometimes around front of the rib cage, and sometimes side of rib cage.  Abdominal pain with this is minimal, however, at times just a little ache.  The pain with this can only be described as a dull, burning ache, never sharp in nature.  I'm able to sleep pain free.  A quick history, treated for H-pylori in April, Laparoscopic gallbladder removal in May.  Original ultrasound before surgery on gallbladder showed only the gallstones, liver, pancreas, spleen, and kidneys were normal.  This ultrasound was done about a month ago.  After surgery, had an Upper GI to rule out ulcers, etc.  That too was normal.  Blood work looking for liver, kidney, and pancreas abnormalities was all normal.  Had a CAT scan done last week and it showed a small right renal cyst, which my doctor assures me is not worrisome...however, what does worry me is this.  The scan showed a 4 cm prominence anterior to the left kidney near the tail of the pancreas.  Report says "liver, spleen, and pancreas are normal.  The 4 cm prominence most likely represents loops of unopacified bowel."  Both of the doctors I work with assure me that it is probably just that, but to have an ultrasound to make sure.  I am somewhat comforted that my initial US was normal in this area, however, I'm still a little worried.  I go for the ultrasound tomorrow and I'm really pretty nervous about it and of course my pain seems much worse having to wait the weekend for the test!!  Any ideas??
