I'm sorry to hear you're experiencing a blocked nose and throat congestion. These symptoms are common with colds, allergies, or sinus irritation.

A nasal spray containing a decongestant like xylometazoline can help relieve nasal blockage by narrowing blood vessels in the nasal passages, reducing swelling and congestion. However, such sprays should be used carefully and only as directed by a doctor, typically not for more than a few days to avoid rebound congestion.

Here are some general tips to ease your symptoms:

• Use a saline nasal spray or rinse to help clear nasal passages.
• Stay hydrated by drinking plenty of fluids.
• Use a humidifier to keep the air moist.
• Rest and avoid irritants like smoke.

If your symptoms persist beyond a week, worsen, or are accompanied by high fever, severe pain, or difficulty breathing, please consult an ear, nose, and throat (ENT) specialist promptly.

For personalized advice and safe treatment options, I recommend seeing an ENT doctor who can evaluate your condition and suggest appropriate therapy.
