Sam I don't know about
others, but Yes at times this pain on the right hip bone is because of UC. It is quite common with my younger brother, who too suffers from UC and my sister. After 4 to 6 years of UC, one gets this pain. I am not sure, if it is the same in your case or it is some ladies problem. Don't worry - it he has put you in it, he will put you through it.
