I understand your concern. Redness of lips or hyperpigmentation as we medically call it may occur due to a wide variety of problems ranging from any physical illness like anemia, skin disease, use of cigarettes drugs or alcohol, or even by taking medications like antibiotics. Proper evaluation to rule out the above conditions is vital before coming to a conclusion. So there is no reason for you to think and unnecessarily worry that ur problem may be due to
hiv only. Your anxiety is easily manageable with appropriate treatment. Some counselling sessions along with medical help also might be useful for you. I would also be more than happy to help you with that if you are looking for online assistance. Discussions will be held confidential. You can directly consult with me through Practo as needed. Online chat consultation is also available.
