I have had lower left torso pain for about three months. No blood in stool. And the pain is not really too bad. Just enough for me to notice. I have had night sweats a few times lately, but not excessive.

I have been under an extreme amount of stress for the past ten months. Can stress onset IBS or other issues?

I have a colonoscopy on Tuesday. I just want to find out.

I also urinate more frequently and doc said that it might be stress. My prostate is good.

I am a 39 year old male in excellent health. I run 40 or more miles per week and don't drink much and have never smoked.

Any thoughts from anyone?
