My 10 month old has a red ring around her ankle that looks like it would be related to her sock line (however, she does not wear socks). It goes half way around her right ankle on the outside. It is raised but does not burn or itch. It has been there going on 5 days and has not faded at all. The pediatrician was somewhat baffled but lead me to believe it may be an allergic reaction. She possibly grazed up against something he assumed. Said since it's not bothering her to just watch it and see if it goes away. I disagree. It's concerning to me that it has been 5 days and has not faded one bit. Could it be something more?
