Gosh I'm sorry to hear you are going through this, how hurtful of your mother to say something like that . Perhaps it is a sebaceous cyst? My RB Cody started getting those here and there when he was 6 or 7 I think.. I can't remember when we found the first one, but I know they are common and totally benign.

You and the pups will be in my prayers, I hope you are able to get through this soon and get peace of mind, and know Kaedyn will be just fine. {{hugs}}
