There was pain in the left side abdomen area the homeopath sugessted it culd b swelling in colon 6 yrs ago I did the colonoscopy reveld nothing so....?

See your doctor. A colonoscopy 6 years ago would not be helpful for recent abdominal pain. You need a thorough physical exam followed by blood work or imaging (ct scan). A repeat colonoscopy may be warranted based on the above results.
Get checked again. Then was then, now is now. Get checked again, may not need another colonoscopy.
