You blew your nose and it hurts bad inside nostril why?

There could be several reasons why your nose hurts badly inside the nostril after blowing it:

Trauma to the nasal tissue: Blowing your nose vigorously or too frequently can cause trauma to the delicate tissues inside your nostril, leading to pain.

Inflammation: The act of blowing your nose can cause irritation and inflammation of the nasal passages, which can result in pain. This inflammation may be caused by the presence of allergens, cold and flu viruses, or excessive use of nasal decongestants.

Dryness: Blowing your nose can remove the natural moisture from your nostrils, causing dryness and irritation. Dryness can lead to cracks or sores inside the nose, making them prone to pain and discomfort.

Sinusitis: If the pain in your nostril is accompanied by symptoms such as facial pain, nasal congestion, and thick nasal discharge, it could indicate sinusitis. Sinusitis is an inflammation of the sinuses, the air-filled spaces around your nose and forehead.

Foreign object: In rare cases, pain inside the nostril after blowing your nose could be due to a foreign object, such as a piece of tissue or a small object, lodged inside the nostril.

If the pain persists or is severe, it's advisable to consult a doctor for proper evaluation and treatment. They can determine the exact cause of the pain and recommend appropriate remedies. In the meantime, try to avoid blowing your nose too forcefully and use saline nasal sprays or gels to keep your nostrils moist.
