... of kidney illness/issue. Obviously they looked into it and eventually found that i was the only one of us that actuall had a problem they could find and fix. So they operated on me and fixed up my kidney (or whatever) and as i recovered, so did my twin sister! To this day we both get sympathy pain for the other and sometimes we can feel each otherss emotions. Thatss my fav story about us. Sorry for the lack of medical knowledge.
