[|Human|] Good evening, I just noticed on my 8month old back that seems to be lump. After further investigating it seems as though it might be an extra rib. Is that normal? Can it be an extra rib? It s only on his left side. As I was messing with it, it didn t seem like it was hurting him. I m freaking out because I have no idea what it can be. His next pediatric appt isn t til august. Should I call to make an appt? Can it wait? Should I wait? What happens if it is an extra rib? Why does that happen? How did it happen? Could it be something I did during pregnancy?
[|AI|]  Thanks for posting... firstly, how are you sure that it's an extra rib? Have you done an x-ray? Extra rib on one side if asymptomatic will not cause any problem, you need not worry. However, there may be associated vertebral anomalies which needs to be ruled out in an x-ray... the X-ray if posted will be helpful... you can wait. Its usually congenital... no, it's not related to something that you did during pregnancy..... lastly i don't think that is an extra rib or your pediatrician would have noticed it earlier.
