If you have herpes on the corner of your mouth, keep the area clean and dry. Avoid touching or picking at the blisters as this can spread the infection and cause scarring. You can apply an over-the-counter antiviral cream or ointment to help speed up healing. Take pain relievers if needed to reduce discomfort. Drink plenty of water and eat a healthy diet to boost your immune system. Avoid spicy, acidic, or salty foods that can irritate the blisters. If the herpes is severe or doesn't improve, consult a doctor. ???? Some natural remedies like applying tea tree oil or aloe vera gel may also provide relief. ????
