<s>[INST] I have a hematoma as the result of surgery to remove my appendix.. The operation took place 3 weeks ago and although I was advised that it may dissipate naturally  the swelling and hardness has barely reduced (akin to having part of a softball sticking out of my side).. I was quite heavily bruised all around the front and side waistband area following the surgery but this has greatly improved. However, the hematoma remains.  I would be grateful if you could advise on possible next steps. Does it just require patience on my part?Many Thanks [/INST] Sometimes, because of continuous bleeding from small blood vessel, there will be hematoma after any surgery. As your surgery was 3 weeks ago, it should get subsided by now. Please go for an Ultrasound abdomen and see the nature of the swelling. If it contains fluid, it could be hematoma. Sometimes, after healing of the wound, there will be induration which will be hard. So, get it confirmed by ultrasound abdomen. IF hematoma is confirmed, please get it Chat Doctor. Wish you good healthRegards </s>
