I have been having this dull pain that started about a week ago, its like this dull knot kind of feeling under my left rib cage that I usually cannot feel until I move a certain way or stretch, the other thing is that my left rib cage is now sticking out a little bit further than my right one which is kindof scary, also I smoke and have a drinking problem. thank you
Since you are experiencing the pain when moving and you find your ribs swollen (there are many causes that may lead to ribs swelling), it is very possible that the pain is resulting from some musculoskelatal disorder of your ribcage.
Another thing that needs to be taken into consideration is enlarged spleen or swollen spleen.
This condition leads to upper left abdominal pain or pain under the left rib cage, that is dull in quality.
