severe abdominal pain

  I have an oncologist, ob/gyn, & GI - each doctor keeps referring me to the other.
  me to the other. Two years ago, I had gastorintestinal
  stromal tumor removed & have been told my abdominal pain
  is not related to this.
  For the past year, I have severe abdominal pain right
  before or right after my period. The pain starts out
  mild & increases over a day or 2. My stomach swells
  and it makes very loud gurlgling sounds, even though
  I have eaten.   My stomach & thighs breakout in small
  red blister-like spots (clears up the next day), & there
  is back pain.I was given a stronger birth control pill but
  that seem to make matters worse.
  I have had CT scans, ultrasounds, and Upper GI & small bowel tests that
  are all normal. The tech. that did the Upper GI felt it
  was endometriosis, the GI thinks its gyn, the gyn thinks
  its GI and The oncologist feels it has nothing to do with
  the tumor.
  It's frustrating because the pain is so
  severe, I miss at least two or three days of work
  a month. I feel like the doctors don't
  believe me. _______________
  Any ideas of what can be causing this pain? Thanks.

Dear mm,
the temporal relationship between your symptoms and mense suggests a hormonal etiology.  Endometriosis is one possible explanation that might require laparoscopic evaluation. Hrmonal changes can also affect gastrointestinal smooth muscle causing symptoms.  You may wish to arrange a conference dscussion with these two doctors to discuss the next steps.
