If it is reoccurring, go to a doctor. A one time occurence is usually nothing.

Hi there. I have been having constipation problems on and off for a couple of months now. I also get pain under my rib cage and pain in my lower abdomen (on the lower left side of the belly button). I sometimes feel like something is lodged in the lower left side of my abdomen and I don't really know what the signs are for colon problems/cancer. I don't have any rectal bleeding--just abdominal discomfort and pain in the lower abdomen/accompanying the constipation problems. I just started having the constipation problems this year (i didn't always have it). I had a colonoscopy done a couple of years ago---way before I had these problems and everything was fine (except that I didn't have these symptoms before then.) can someone on here help provide me with any useful advice of what this could be and tests that could be done to see what this is (colon or other)? I would greatly appreciate it. Thanks.
