Why Did My Nose Suddenly Swell Up Without Any Obvious Cause?

The nose is located in a prominent position, and it is prone to swelling when subjected to trauma. However, some people may still experience nasal swelling without any trauma. This could be due to nasal furuncle, folliculitis, internal heat, and other reasons. It is recommended to identify the cause based on one's own condition and receive targeted treatment accordingly.

Why Does the Nose Swell Spontaneously?

1. Nasal Furuncle: It is often caused by picking the nose, pulling nasal hair, or trauma to the nasal vestibule or external nasal skin appendages, which leads to secondary bacterial infection and nasal swelling. Generally, antibiotics are required to treat bacteria and swelling. It is advisable to avoid squeezing the nose to prevent deep swelling. Additionally, avoid excessive squeezing of the nasal cavity to prevent intracranial infection caused by cavernous sinusitis.

2. If it is folliculitis, it is caused by an infectious inflammation. In this case, anti-inflammatory medication is also necessary to prevent the condition from worsening. Topical anti-inflammatory ointments can be applied. It is important to maintain a balanced diet, avoid spicy foods, drink plenty of water, and eat fruits and vegetables to supplement vitamins. Attention should be paid to balancing work and rest, and avoiding staying up late.

3. Internal heat can stimulate local capillary dilation and congestion, and other causes such as bacterial infection can lead to nasal redness and swelling. If there are pustules on the nose, do not squeeze them as they indicate inflammation. Improper handling may lead to infection and exacerbate the condition. It is advisable to avoid spicy, greasy, and stimulating foods, eat more vegetables and fruits, and maintain regular bowel movements. Bad habits such as picking the nose should be avoided, and various nasal diseases should be actively treated to keep the nose clean.
