Boils on the lips can be caused by bacterial infection, clogged glands, poor hygiene, or weakened immunity. Cold sores from viruses can look similar. Keep the area clean, avoid picking, and consult a doctor if they are painful, recurrent, or not healing.

Since these red patches have persisted for six months, it is crucial not to self-medicate with over-the-counter ointments, as the wrong treatment can worsen the condition. While herpes typically presents as painful blisters that heal within weeks rather than lasting continuously for months, other conditions like balanitis (a fungal or bacterial infection), eczema, or psoriasis are highly possible. I strongly recommend consulting a urologist or dermatologist. They can perform a physical examination, take a swab test if necessary, and prescribe the correct targeted treatment?such as a specific antifungal, antiviral, or mild steroid cream?based on an accurate diagnosis.
