<s>[INST] I have a raised region on left side just below ribs. I went to the doctor he felt my abdominal region said there was nothing to worry about. However I still have this lump or swollen area. It s not painful but sometimes uncomfortable I have to lift my left shoulder up. I m thinking it could be my posture but this wouldn t cause swelling. It s slightly noticeable what could it be?? [/INST] Hi, as mentioned by you, about the swollen or lump area, and also examined by doctor where he said It's nothing to worry.of course I agree to you that how come something comes up like this and is painful. And also how come the swelling is persisting. What I would suggest is to undergo an x-ray and check as it may reveal something with it. Maybe a fluid accumulation. Also, later on an MRI will guide to see what soft tissues are involved in that area leading to swelling. Until we get a picture of the soft tissue abnormality it will be really tough for anyone to examine and comment. As diagnostic holds the strong ground for assistance. I wish you get an MRI done, so we can come to know what sort of soft tissue is involved a muscular or a lung tissue. With the grace of God I wish you a speedy recoveryregardsJay In Chat Doctor.  </s>
