DS has had a growth spurt recently and as a result he lost a lot of puppy fat. Tonight he had no shirt on and his left side lower rib cage is notably more indented than the right. I’ve never noticed this before and he’s gone through periods of being slim getting a bit chunky before slimming out with his next growth spurt.
I’m concerned it could be a sign of something more serious like scoliosis anyone had similar with their young teen?
