Sinus infections (sinusitis), allergies, and regular nasal congestion share some common symptoms, but they have distinct differences. Here's how you can tell them apart:

1. Sinus Infection (Sinusitis) Symptoms:

• Facial pain & pressure (around the forehead, cheeks, eyes, or nose)
• Thick, yellow, or green nasal discharge
• Sinus headache (worse when bending over)
• Fever (often present)
• Bad breath (halitosis)
• Cough (worsens at night)
• Ear pressure or pain
• Fatigue
• Symptoms last more than 10 days or worsen after initial improvement

2. Allergies (Allergic Rhinitis) Symptoms:

• Clear, watery nasal discharge
• Sneezing
• Itchy nose, eyes, throat, or ears
• Watery, red eyes
• Postnasal drip (mucus in the throat)
• Worsens with exposure to allergens (pollen, dust, pet dander, etc.)
• No fever or facial pain

3. Regular Nasal Congestion (Cold or Irritation):

• Runny or stuffy nose (clear mucus)
• Sneezing and mild cough
• Sore throat
• Mild body aches or fatigue
• Lasts about 7-10 days

Key Differences:

Symptom	Sinus Infection	Allergies	Cold (Nasal Congestion)
Nasal Discharge	Thick, yellow/green	Clear, watery	Clear or white
Facial Pain/Pressure	Yes	No	Mild/None
Itchy Eyes/Nose	No	Yes	No
Fever	Sometimes	No	Sometimes (low grade)
Duration	10+ days	Seasonal or ongoing	7-10 days
Cough	Worse at night	Sometimes	Mild
Triggers	After a cold or infection	Allergens (pollen, dust)	Virus

If symptoms last more than 10 days or worsen after improving, it may indicate a bacterial sinus infection that could require antibiotics. Let me know if you need advice on treatments!
