Crusty sore on my lip won’t go away. Appointment is impossible to get right now. What is this?

Although it’s rare, a persistent lip sore can sometimes be a sign of a type of skin cancer called squamous cell carcinoma. This condition often looks like a scaly patch or a lump on the lip that won’t go away. Factors like spending a lot of time in the sun and smoking can increase your risk. Finding it early is key for successful treatment. If a sore doesn’t get better or seems to be growing, a doctor might need to do a biopsy to check for cancer.

Other Possible Reasons

• Autoimmune Disorders: Conditions like lupus or pemphigus vulgaris can cause stubborn sores on the lips and other soft tissues in the mouth. These happen when your immune system mistakenly attacks your own healthy tissues, leading to long-lasting inflammation and sores. Doctors usually diagnose these with blood tests and give patients medications to manage symptoms.
• Vitamin Deficiencies: Not getting enough of certain vitamins, especially B vitamins like B2, B3, and B12, can lead to sores on the lips. This can cause angular cheilitis, which is known for painful cracks and crusty spots at the corners of the mouth. Eating a better diet or taking supplements can help. A healthcare provider can give you advice on what changes to make.

What You Can Do at Home

Many people try home remedies to get relief from lip sores. Things like applying aloe vera, honey, or coconut oil can help soothe and moisturize your lips. Using a cold compress can also help reduce swelling and discomfort.

While these home remedies can provide temporary relief, you should still watch the sore to see if it’s getting better. If it doesn’t improve, it’s best to seek professional advice. Over-the-counter (OTC) treatments can also help with certain types of sores. Antiviral creams, like docosanol, can shorten the life of a cold sore. Antibacterial ointments can be useful for small cuts and infections. Always follow the directions on these products and ask a pharmacist if you have any questions.

When to See a Doctor

If your lip sore is not getting better after you’ve tried home care and OTC treatments, it’s important to get professional medical advice. A doctor can do a full exam and might run tests to find the real cause.

We know how hard it can be to get a timely appointment, but being persistent is the most important thing you can do. Using telemedicine services or going to a clinic that has shorter wait times might help you get seen sooner. Getting help early can lead to a more effective treatment and help you avoid any possible complications.
