My teenage son has a solid lump under his left side of rib cage, he also has some swelling in the middle of the bottom of his ribs, he is tired and uncomfortable, his blood tests showed nothing, what could this be, Dr has referred for an urgent scan.
Hello, It could be a bony swelling like Osceola. Consult a physician and get evaluated. Most probably it has to be excised under local anesthesia. Hope I have answered your query. Let me know if I can assist you further.
