Hi, I have noticed just as of the past few months that I will have red dots and lines appear suddenly around my cheeks, eyes and chin areas. They are not bumpy, itchy, or scabby, But i have noticed my face will feel warm. They will appear and then after about 20 minutes just disappear slowley. I have noticed that they accure when i get nervous and or stressed. Please tell me what it is and why i am getting them.
