Flat purple dots on 4 year old's chin
This morning my four year old some how developed a cluster of small flat purple dots under her bottom lip. It looks like a maker blew up in her face but the dots won't wash off. All day she has acted normal, there has been no changes in her eating habits or anything else. There has been no increase or decrease in the dots since this morning. I called her dr's office and they said it could be heat rash but they weren't 100% sure on what it was and that I should just keep an eye on it. I don't believe that it's heat rash because the area is smooth and not bumpy at all and the dots are purple not red. I have never seen anything like this before and it's starting to concern me. So if anyone has seen this before and knows what could have caused these dots please let me know.
Thanks for any help.
