Lower left side (flank) back pain every 5-7 days

I am a 22-year-old male, 6'2", 128 pounds. In June of 2001, I started experiencing pain in my lower left back (off to the left side). The pain is best described as very similar to a stomach ache (cramping, dull yet intense pain unwavering in intensity). Each pain episode lasts 12-18 hours.  The pain disappears at hour 12-18 if I lie on my side with my knees bent, such that my left hip bears the weight.  If so, I experience a gurgling noise (which sounds like stomach rumbling), except the sound originates from the lower left back/side, along with a spasmic/pulsating sensation. 15 seconds and the pain is completely gone, with no remaining symptoms. The pain occurs every 5-7 days, but has not been continuous since 2001. I experienced the pain every 5-7 days in June 2001, May-June 2002, March-July 2004, and July 2005-present.

GI causes for pain in the left side can include various causes of dyspepsia (i.e. ulcer, inflammation of the upper digestive tract, GERD), pancreas disorders, or irritable bowel syndrome.  If the pain is lower down on the left side, diverticulitis can be considered.  

The CT showed an enlarged left kidney - but would also evaluate for kidney stones (which can also cause the pain).

You can consider further evaluation with an upper endoscopy to evaluate the upper digestive tract, or a CT scan of the abdomen to evaluate the pancreas.  Blood tests looking at the pancreatic enzymes can also be considered.

If there is a foul taste in the mouth, GERD can be considered.  If the upper endoscopy is non-revealing, you can consider a 24-hr pH study to definitively rule in or out GERD.

These options can be discussed with your personal physician.

Followup with your personal physician is essential.
