What should I do about small white pus-filled spots inside my nose?
If you notice small white pustules or pus-filled bumps inside your nose, they are most commonly caused by localized bacterial infection—often Staphylococcus aureus—involving hair follicles or sebaceous glands in the nasal vestibule (the area just inside the nostrils). This condition is known as nasal vestibulitis. It may appear as tender, red, raised lesions with a central white or yellowish head, sometimes accompanied by crusting, mild swelling, or discomfort when touching or breathing through the nose.
It’s important to avoid squeezing, picking, or attempting to drain these lesions yourself. The nasal vestibule has rich vascular connections to the cavernous sinus—a critical venous structure near the brain—and improper manipulation can potentially lead to serious complications, including cavernous sinus thrombosis, though rare. Instead, gentle warm compresses applied externally for 10–15 minutes several times daily can help promote natural drainage and reduce inflammation.
Over-the-counter topical antibiotic ointments—such as mupirocin or bacitracin—applied sparingly with a clean cotton swab two to three times daily may aid resolution, especially if used early. However, avoid prolonged or indiscriminate use of antibiotics to prevent resistance. If lesions persist beyond 7–10 days, worsen (e.g., increasing pain, spreading redness, fever), recur frequently, or involve multiple sites, consult an otolaryngologist or primary care provider. They may perform nasal culture, prescribe oral antibiotics (e.g., cephalexin or clindamycin), or evaluate for underlying contributors such as chronic rhinitis, immunocompromise, or nasal carriage of methicillin-resistant Staphylococcus aureus (MRSA).
Preventive measures include avoiding nasal trauma (e.g., from aggressive nose blowing or digital manipulation), keeping fingernails trimmed and clean, using saline nasal spray to maintain mucosal moisture, and addressing any underlying allergies or chronic sinus conditions that may predispose to recurrent irritation or infection.
