Back pain is very common among adults. Many of them go to the doctor and the doctor can’t find anything specific – no slipped disc, no breaks, nothing obvious. But, the back still hurts and it still interferes with every day life. While back pain is not as common among children as in adults, it can have the same properties – the doctor may not be able to find out what is causing it. This is called non-specific back pain. This doesn’t mean that your grandson doesn’t have back pain. It just means that the doctor can’t find a cause for it.
