[|Human|] My son fell down the stairs and landed with a step in the middle of his lower back. It bruised right away, should i be taking him to the doctor? He got up right away the brusising is going down and he says it doesnt hurt as bad now its been about and hour and half since he fell.
[|AI|]  Hi, Actually I don't think it will need a doctor unless it persists for more than a week or causing pain or inability to do his daily activities. If so you may ask your physician for imaging like x-ray, CT and physical evaluation. For now, you may start icing it for the first 48 hrs, applying topical gels is relieving and good for the bruising. Make him rest and avoid vigorous actions and rest well. Advil tab twice per day after meals in addition to acetaminophen is recommended, and Trypsin if there is persistent swelling. I am sure he is fine and he won't need any more care. Hope the above information helps you. Any further clarifications feel free to ask.
