<s>[INST] Hi, i was pushed into the top end corner of a couch and bumped the side of my hip. Its  just above the hip bone and theres a hard lump like 12 centremetres long going across. Im worried because on the first day i got it i couldnt pee,poop,cough light with out it being so painful im scareddd! [/INST] Hi, Welcome to Chat Doctor. Looks like you have got a hematoma (blood clot) following the bump. It occurs when there is an injury to a vessel following trauma, leading to collection of blood in the region. It will get absorbed slowly but will take a few weeks in this process. You may take painkillers for your pain. But keep a watch over the swelling, and on case it becomes more painful or red you will need to get it removed, as that means that it has got infected. Hope I have been helpful. Regards </s>
