Periodic gut pain, salivating & nausea

[JGK55]

I am 52, male and active.
Periodically I get a really sharp pain in the lower left quadrant of my gut.  
It doubles me over and I have severe diarrhea.
It also makes me salivate profusely and occasionally I throw up.
Once I have evacuated the pain, salivating and nausea goes away.
I have kept logs but couldn't pin down a culprit.

It has happened every 6 months or so for the last 25 years.
If anything it may be increasing in frequency  but not much.  
A few years ago I had a whole raft of tests but nothing was found.
It didn't fit into IBS and the only theory was stress or food related.

Its a tough one as by the time the doctor saw me there is no pain or even tenderness.  
Hard to diagnose something that isn't there.

I would appreciate any ideas/thoughts/theories.

That's strange....it sounds like IBS to me.  Or some sort of food intolerance.  Does it happy when you eat certain foods?  Or does it happen when you are upset or stressed?  It could also be a gluten allergy.  Do eat a lot of bread?  I would have yourself checked again.  Maybe and colonoscopy since the pain is on the left lower quadrant.  That pain is associated with the intestines.

I have had a colonoscopy...no problems. (aside from that gallon of stuff I had to drink).
This happens really infrequently and I have tracked my food around these episodes and there seems to be no smoking gun.  I do eat bread but not a huge amount but 99.9% of the time I don't react/have the issue.  Weird.  I'm beginning to think someone has a voodoo doll and a sharp pin.

John,

I have experienced the same symptoms, 3-4 times total, and each time it woke me in the middle of the night, sharp pain in the pit of my stomach, combined with nausea and severe salivation. My mouth just waters and waters, I feel either hungry or like I'm going to vomit, and the pain is sudden and intense.  The episode lasts 10-15 minutes.  It almost seems like the salivation helps the pain?   I'm learning to wait it out and let the salivating, swallowing the extra saliva, ease the pain but I have no idea what causes these episodes.   Have suspected MSG but it happens so infrequently that I haven't logged anything yet to try to find triggers.   I'm a 39 y-o female, this has happened 3-4 times in the last year and a half or so, I don't take any medications other than occasional ibuprofen (often enough to know it is not the cause), have no health problems that I'm aware of other than needing to lose some weight.  I do have a terrible habit of drinking numerous servings (avg. 5-6 cans) of my favorite diet soda daily,and have for years...have been waiting to see what adverse effect there might be from that...wonder if you have any similar habits?  The soda I like is a diet citrus flavored soda.
