For me I had a horrible pain right between my rib cage. It felt like I was stuck in a vice and someone was tightening it. I also had a hard time eating anything greasy, fatty, lettuce, then it got to be anything at all. I was in and out of the ER, but all my lab results came back normal. Turns out I had so many gall stones blocking the bile duct, that nothing could get out. My gall bladder was so infected that I got sepsis during the removal. That was the worst 4 months of my life. I was pregnant when the first signs started showing up, and my daughter was 2mths old when I had the surgery. Between ER visits I was in so much pain that I couldn't nurse my daughter, then I was put on pain meds and had to stop nursing her all together.
My suggestion is to get the problem solved immediately, it is not fun.
