[|Human|] hello. I have an odd shaped lump or growth in my bottom right ribcage. It feels as if it is growing directly on it. It also feels like a deformed rib sticking out. It does not really hurt when I touch it, but it gives me an unusual sensation when I do touch it. It is under the skin. I can feel it whenever I move a certain way.
[|AI|]  Hi, There are a couple of things that come to mind. One is called a lipoma and that may be the most likely type of lump or nodule. Another thing that comes to mind is something called a neuroma. The first item is a tumorous growth of fat tissue (entirely benign and noncancerous) and the 2nd is a tumorous growth of nerve tissue (again benign).  Lipomas are never painful unless they are overriding a sensitive structure such as a nerve.  Neuromas are often painful when squeezed or compressed but if you leave them alone they'll do the same. In either case, it wouldn't be a bad idea to have a doctor take a look (and a feel) just to make sure all is in order.  Hope I have answered your query. Let me know if I can assist you further.
