It's hard to say Andy.
interestingly I have been having similar pains and had an unltrasound today. No results yet.
IN my case I am not having any [wiki2="Crohns-Disease"]Crohns[/wiki2] related symptoms and the doc thinks it is muscular skeletal. I am not sure.
It could be so many things. Appendicitis, gall bladder...
BTW The descending colon is on the left side so why pain on the right?
Good question no?
Are you having any other symptoms?
Diarrhea, nausea, [wiki2="Blood-in-Stool"]blood in stool[/wiki2], Loss of appetite?
You may need a lot of tests and exams to get the diagnosis right.
Have you had blood work done? That can give you a better idea.
Be thankful it is not cancer and hope for the best.
Let us know how it goes then maybe we can be f more help.
Good luck.
