I'm sorry to hear that you're having trouble breathing due to a blocked nose despite using a nasal spray. Nasal sprays like Nosikind-0.1% (which contains xylometazoline) work by narrowing the blood vessels in your nasal passages to reduce swelling and congestion, providing temporary relief.

However, if your nose remains blocked after using the spray, it could be due to several reasons:

• Overuse or prolonged use: Using nasal decongestant sprays for more than 3-5 days can cause rebound congestion, where the nasal passages swell again, making blockage worse.
• Underlying conditions: Allergies, sinus infections, or structural issues like a deviated septum can cause persistent nasal blockage that may not fully respond to sprays.
• Incorrect usage: Not using the spray properly or not following the prescribed dosage can reduce its effectiveness.

If you experience persistent blockage, burning, dryness, or sneezing that does not improve, it is important to consult an ear, nose, and throat (ENT) specialist. They can evaluate your condition, rule out infections or other causes, and recommend appropriate treatment.

In the meantime, you may try:

• Using saline nasal sprays or rinses to keep nasal passages moist.
• Avoiding overuse of decongestant sprays.
• Keeping hydrated and using a humidifier to ease nasal dryness.

If you have difficulty breathing or severe symptoms, please seek immediate medical attention or contact emergency services.

Always follow your doctor's advice regarding nasal spray use and consult an ENT specialist for persistent nasal blockage.To narrow down potential causes, we will need some more information.Please tell me your age and gender.
