I'm sorry to hear you're experiencing a cold, cough, and nasal congestion. These symptoms are common with upper respiratory infections and can be quite uncomfortable.

For relief from nasal congestion and irritation, a nasal gel containing sodium chloride, such as Nasoclear Gel, may help. This gel moisturizes the nasal passages, loosens thick mucus, and can ease breathing. It is applied inside the nose and is generally safe, but avoid consuming it. Some mild side effects like sneezing or a stinging sensation may occur but usually resolve on their own.

Here are some general tips to manage your symptoms:

• Stay well hydrated.
• Rest as much as possible.
• Use saline nasal sprays or gels to keep nasal passages moist.
• Avoid irritants like smoke or strong odors.
• Over-the-counter medications may help with cough and congestion, but consult a doctor before use.

If your symptoms worsen, persist beyond 10 days, or you develop high fever, difficulty breathing, or chest pain, please seek medical attention promptly.

I recommend consulting an ear, nose, and throat (ENT) specialist or your primary care doctor to evaluate your symptoms and guide appropriate treatment.To narrow down potential causes, we will need some more information.Please tell me your age and gender.
