Do I have chrons or just IBS?

by Catherine Roberts

I have 2 cousins with chrones and was diagnosed with IBS at 15. After years of no problems ( I am 42) I now have developed constant indigestion/stomach discomfort. When I am unwell it makes me feel nauseous and cold. I also have tenderness like internal bruising/stitch in my lower right abdomen. All these symptoms will come and go within minutes and stay or stay away for several days.
I sometimes have constipation but very little loose bowel movements bur often see mucus. Could I like my cousins have chrones? My fathers side is of Jewish blood too

Thanks
