Hello, Thank you for contacting me at Ask a Doctor . I will try to answer your question to the best of my ability. I am sorry about your daughter s accident. I hope that at this stage she is feeling a little better. From your story it does not sound like anything too serious. I would continue with the Motrin for the moment. Applying a little ice for pain relief is also beneficial. If she feels a lot of stiffness in the back area you may also want to try some local applications of heat. If she feels a little better tomorrow you could continue with the above treatment. If she feels considerably worse, then certainly a visit to her primary care doctor would be a good idea. I hope this information is useful for you. Please do not hesitate to message us back if you have any further questions. Best wishes, Adrian Rawlinson MD
