What causes sores inside the nose?

Answer

According to the National Cancer Institute, sores inside the nose that do not heal can indicate nasal cavity cancer. Additional signs of nasal cavity cancer include headaches and pain in the sinus area, nosebleeds, lumps inside the nose, pressure in the ear and numbness or tingling of the face. It is important for anyone experiencing sores in the nose to consult with a physician to ensure an accurate diagnosis.

The Lupus Foundation of America explains that sores inside the nose are a common symptom of lupus, an autoimmune disease. Sores in the nose due to lupus are referred to as mucosal ulcerations and can also be found in the mouth and in vaginal tissue lining. In most cases, lupus ulcers do not cause pain and can resemble cold sores.

According to WebMD, sores around the nose are a symptom if impetigo, a condition that is common in children. Impetigo is caused by bacteria and often coincides with allergies and colds due to the fact that constant rubbing of the nose can create raw skin, making it easier for bacteria to enter the area; however, impetigo can develop on healthy skin. Impetigo sores are red and painful. The sores often ooze fluid and form crusts. Impetigo is diagnosed by visual examination and lab cultures that detect bacteria.
