Hi,
You have likely developed an infection or injury inside your left
nostril, causing pain, swelling, increased mucus production, and tenderness when touched. You may have a nasal abscess, a cut or a sore inside your nostril, or even a
sinus infection.
To get a proper diagnosis and treatment, I recommend you to see a doctor or a specialist in ear, nose, and throat (ENT). They may perform a physical examination, ask about your symptoms and medical history, and potentially run tests, such as a CT scan or a culture of any discharge, to determine the cause of your symptoms.
In the meantime, you can try to reduce the pain and swelling by applying a warm compress to the affected area, taking over-the-counter pain relievers, and keeping your nose and
sinuses moist by drinking plenty of fluids and using a saline
nasal spray. However, these are just temporary measures, and it's essential to seek
medical advice to address the root cause of your symptoms.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Priyanka, General & Family Physician
