I Get A Dull Pain In My Git Just Below

I get a dull pain in my git just below my right rib from time to time, I feel it more when I bend over or push on it. I am dealing with it right now and I wonder if it is related to the fact I have had more meat than normal the last couple of days (including yesterday) and I did over indulge on some Hamburger Helper to the point of being uncomfortably full.
My health history: I am a 30 year old female, overweight, and have had a scope done due to bloody stools just under a year ago and was diagnosed with diverticulitis. (I have since not had an episode of blood and upped my fiber intake by a lot, I also for the most part cut back on meat)
So my question is: am I feeling stool passing a sore spot in my large intestine? Maybe I have a hernia? Is this liver related? This pain concerns me every time it happens, more so right now as I am leaving town for a week at dawn tomorrow/Wednesday.
