I'm 24 weeks now. The past three days I've had a pretty extreme pain under my right rib cage. Sometimes it'll settle down and won't be so bad but most of the time, it's really bad. It feels like pressure, like something under my ribs is being blown up, there is even a lump at times under my ribs(right side only). I know it couldn't possibly be the baby just because I always feel him somewhere else when the pain gets to be at its worst. Please let me know what I should be doing, I'm almost getting very worried.
