I just took my baby to the doctor today and they scheduled an Echo for Wednesday. They want to check her for Perioral Ecchymosis...Or something like that, I dont know anything about it, they didnt inform me about it they just told me to watch for trouble breatheing and blueness. But I dont know what it is, or what it does, and I cant seem to find anything on the internet about it. Can someone please help me? Thanks.
