<s>[INST] I am 28 years old and approximately 112 lbs. 4 feet 11 inches tall. The only medical history I really have is depression, 2 c-sections, and tonsil and adnoid removal. I found a hard lump on my ribs and I wouldn t say tender to the touch, but more painful to touch. [/INST] Hi, dairy have gone through your question. I can understand your concern. You may have some soft tissue tumor like dermatofibroma or neurofibroma or some bone tumor.  Yous should go for x-ray local part first.  Then if needed go for biopsy of lump.  It will give you exact diagnosis. Then you should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health. </s>
