### input:
I have been feeling movement under my rib cage, not painful, just strange.  Then a few days later, I went to bed, I had extreme pain in my lower stomach area, well below my belly button, that was only relieved by laying on my back. That eased enough for me to sleep, but when I got up the next morning, there was a bloated feeling in my upper abdomen where the movement had been, that stayed all day.  Bowels acted completely normal, not constipated or diarrhea, but do feel a little gassy, but that is passing normally, not really easing the discomfort under my rib cage.  Not painful or nauseous, just really uncomfortable, completely unusual for me.  I am 50 years old, female, pre-menopausal, obese, but otherwise completely healthy, normal blood pressure, sugar levels, cholesterol, triglycerides, had hernia repair six months ago, and that was the most serious health issue of my life.

### output:

Hello! Thank you for the query.It's hard to answer your question not knowing what kind of hernia was repaired. If it was abdominal hernia and abdominal cavity has been opened, adhesions or hernia recurrence is possible. As you are 50 years old and obese, this makes colon cancer possible (obesity increases the risk of it). And such symptoms can be caused by large intestine issue as well. That is why I suggest you to visit your surgeon and check for possible hernia recurrence. Abdominal ultrasound should be done. No matter if the hernia is or not, you should also have colonoscopy done. Hope this will help. Regards.
