Pain in my lower right abdomen?

I have been having achy pains in my lower right abdomen. My appendix was trmoved about 3 yrs ago so not that. It will come on real sudden and VERY strong. At times its hard for me to move. Its right where hip meets thigh... You know that crease area. I've not moved anything heavy and I don't remember pulling anything there, but either way it feels different than muscle pain. Any ideas would be great! I can't get in to see the dr for another 2 wks as my schedule is completely full till then.
