What Causes Sores in the Nose?

Nasal cavity and paranasal sinus cancer can cause sores to form in the nose, states the National Cancer Institute. These sores generally don’t heal or do so slowly.

Nose sores, nosebleeds and pain often accompany nasal or nose cancer, explains the National Cancer Institute. Depending on whether the cancer is nasal or paransasal, other symptoms range from blocked sinuses and sinus headaches to numbness, pain and pressure throughout the face. After determining if the sore is a sign of cancer through biopsies, nasoscopies in which the physician views the sore through the use of a thin tube, or MRIs, the doctor recommends a treatment based on the size and stage of the cancer. A patient can undergo radiation or chemotherapy, have the tumors surgically removed or take part in clinical trials.

The herpes virus can also cause sores in or on the nose, states Everyday Health. Along with the sores, a person can experience tingling and itching prior to the eruption of the blisters followed by a sore that oozes and crusts over, says the Mayo Clinic. In some cases, a person also experiences more severe symptoms, such as a fever, sore throat and swollen lymph nodes. If the sores don’t heal after several weeks or frequently recur, the individual needs to consult a medical professional.
