<s>[INST] I have a swollen area on my upper chest - lower neck, near or slightly above collar bone halfway to shoulder. The swollen area is not painful and seems soft and fatty. It seems oval shaped and about the size of a tangerine in width but not depth. I have not had it long. I had a recent accident in which I bruised my ribs and also badly cut a finger. I have no fever and I feel fine. Thank you. [/INST] Hi,Welcome to HealthcareMagic.If you have developed the swelling after accident then that could be due to trauma leading to bleeding which stopped and formed a soft mass called haematoma.I suggest you to consult your doctor and confirm the diagnosis. And get ultrasound done.  Treatment may be aspiration. Hope I have answered your query.Regards Dr Deepika Patil </s>
