<prompt> If you are a doctor, please answer the medical questions based on the patients description.My 11 year old fell off his bike last night. He scraped his left side above his hip bone and we just noticed it s a dark bruise that s protruding quite a bit. It s tender to the touch but he hasn t complained of any intense pain. Any ideas as to whether how serious this might be?  <response>: Hi, Thanks for your queryBased upon your description, I suspect that you might have soft tissue injury. Dark bruise might be due to hematoma formationcollection of blood. You need an x-ray to rule out any bony injury. I suggest you to consult an orthopaedician nearby for a detailed examination. You may get the X-ray of the area affected under hisher guidance. Beside icing and elevating it, you can take anti-inflammatory Chat Doctor. I do hope that you have found something helpful, and I will be glad to answer any further query. Take care
