Hi Dear, welcome to HCM. Understanding your concern. As per your query you have red spots and bumps on lips there can be many possibilities for bumps on your lip like allergic reaction , canker sore , bacterial infection , fordyce granule, mucocoele or it can be ecchymosis because of the trauma like lip biting and herpes . But in your case it seems to me as Herpes or cold sores which occurs because of lowered immunity of body. Need no to worry about it. Visit oral physician once and get oral examination and visual examination done. If its not identifiable then go for culture by taking sample with the help of swab to determine if bacteria, viruses, or fungi may be causing the bumps. If doctor doubts you may have oral cancer, a tissue sample can be collected to test for malignant cells. Use antiviral ointments such as rich in acyclovir. Wash face frequently, only with water without use of any chemical agent. Your symptoms will resolve soon. Cover skin while exposure to sunlight and avoid sun exposure iof possible. Drink plenty water and fluids to re hydrate body. Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Mahehshwari
