I have been having this pain in my colon with some gas. It is on the left side just above my groin. I have attached a picture with circled area where the pain is happening all day. I have been eating very small meals. Also I had about 5 bowels today, all regular, no diahrea. What could this pain be? I hope I do not have a hernia. Only form of strainous thing I did was climb four stiars yesterday rather fast.
