### Patient: Doctor, I have this lump on my arm that is quite painful. It feels like a big bruise, but it has been there for a few days now. What do you think it could be?
### Doctor: I think you might have a hematoma. We should do a few tests to confirm. We will need to perform wound care management to treat the area. Additionally, we will need to perform a complete physical skin exam performed (ML) to check for any other bumps or lumps. We will also need to do a scan ct or X-ray to confirm the presence of a hematoma. It is important to rule out any other potential serious problems, so we will also examine your breast and do an ultrasound. Finally, we will do a blood culture and prothrombin time assay to check for any underlying blood clotting disorders.
