What Causes Tender Lump Under Right Rib Cage?

Under your right rib cage, tissues can sometimes form a lump when there is a weak spot in the abdominal muscles which allows fatty or intestines to protrude outwards from the abdomen. This is called a hernia. This may feel tender when you press on it. Another possibility is a lipoma, which is a soft, usually harmless fatty growth that can form under the skin. Although lipomas are mostly painless, they can cause discomfort if they become irritated. In less common situations, a tender lump could be due to a small tumor growing from the bone or surrounding tissues. These growths may also produce discomfort. It is important to remember that many of these conditions are not serious, but if the lump is painful, growing, or causing you worry, it is a good idea to speak with a healthcare provider. They can examine the lump, perform any needed tests, and decide on the proper treatment.
