[|AI|]  Hi. Thank you for posting your question. Pain after injury to the back could be a due to a few reasons. It could be a muscular pain due to injury to the muscle fibers or simply muscle pull. In this case there shouldn't be any devastating consequences and the pain should be relieved by hot fomentation and painkillers. Here your child should not have difficulty in walking and generally your child should be well. This seems most likely in your case. However, pain could also be due to bony injury to the spine or spinal nerves. In this case, the pain would be much more and would be debilitating enough to prevent your child from moving about normally. Here an E.R. visit is mandatory. Also since you mentioned that your child is able to follow his normal routine, climb a bicycle etc. and the pain starts only after some time, this most likely seems to be a muscular pain. Giving him painkillers with some local relief sprays and hot fomentation should suffice.
