i have a lump under my lower left rib that sometimes causes pain. what is it?
most helpful answer i'm sorry to hear you're experiencing this. it sounds quite unpleasant! unfortunately it's impossible to answer your question in a forum like this because diagnosing the problem requires a physical examination. i suggest you consult your primary healthcare provider for an exam. that said the situation doesn't sound dire. a lump in the area you describe would probably be a nodule in the skin such as a fatty cyst. of course if you're talking about a lump on the ribcage near breast tissue then this would be a concern. but i'm reading your question as a lump underneath the bottom of your ribcage on the left side. at any rate a trip to the doctor is in order to get some answers. wishing you well!
