I am 28 years old I have 3 kids , I am active and live a pretty healthy life , I have been having discomfort and pressure in my lower ribs and back. Kind of like when a woman is pregnant and the baby presses on her ribs is how I could best describe the problem. It tends to worsen after a night of sleep. I am without insurance right now and dread a huge medical bill if it is something simple.!!!!! Anyone have any ideas of what might be the problem???
