<s>[INST] hi, i have been having some health issues for over a year now. weight loss, bloating, gas, pelvic pain, lower back pain, diarrhea on and off, recently had abenign polyp removed from the neck of my womb and 3 colon polyps removed, still waiting on the results for colon polyps, i have a follow up in march 2 get results so they must be benign. well i have had a hard painless lump on my left ribcage between the 9th and 10th rib for over 4 years i think, it doesnt move but im sure its grown some. what do u think it could be? im 37 female [/INST] Thanks for posting your query to Chat Doctor. As I understand you are having problem in different system of body. I tried to save your query .painless lump on rib cage could be a benign mass for which you need to undergo ultrasound and biopsy examination under guidance of Surgeon. Pelvic pain and lower back pain could be due to muscle spasm which require opinion of an orthopedic surgeon. Gastric trouble could be due to your food habits, so you need to manage your dietary habit.thanks . </s>
