The redness and warmth in your cheek and ear could be caused by a condition known as flushing, which is when small blood vessels in your face dilate and fill with more blood, making your skin appear red and warm. Possible causes include medications, rosacea, alcohol, emotional stress, and exercise. Avoiding hot drinks, spicy foods, alcohol, and processed meats can help manage these symptoms. Although flushing may be aesthetically bothersome, it is a normal and temporary physiological response.
