<s>[INST] I have a 4 year old, she spent all day outside with her mom. Now she has a rash just on her upper lip, where a man would have a mustache, it is a pinkish purple color, it doesnt itch, burn or hurt. It isnt raised but it is almost solid across her lip. What should i do? Could it be an allergic reaction? Or irritation from something? I know its not poison ivy, oak or sumac. Should i take her to the doctor now, in the morning, or should i wait and see? She isnt complaining at all. [/INST] Thanks for your query at health care magic.because this rash is not causing any itching its cant be due to allergic reaction. your history more suggestive of trauma followed by collection of some blood under the skin. U may ask her Mom regarding any injury during playing.It is not harmful injury and it will be ok bye few days itself so u should not worry.Hope it will help. For more queries u may contact me at this site.Regardsdr deepak vaishnav </s>
