I'm sorry to hear you're experiencing a cold, cough, and nasal blockage. These symptoms are common with viral upper respiratory infections and usually improve with rest and supportive care.

Here are some general suggestions to help relieve your symptoms:

• Stay hydrated by drinking plenty of fluids.
• Use a humidifier or inhale steam to ease nasal congestion.
• Over-the-counter saline nasal sprays can help clear nasal blockage.
• For cough and cold relief, medications like antihistamines or decongestants may be helpful, but these should be used under medical advice.

Since your symptoms have lasted for 2 days and include nasal blockage, it’s important to monitor for any worsening signs such as high fever, difficulty breathing, or persistent symptoms beyond a week.

I recommend consulting a general physician or an ear, nose, and throat (ENT) specialist to get a proper evaluation and appropriate treatment. They can also advise if a medication like the one you mentioned (which requires a prescription) is suitable for your condition. If symptoms worsen or you experience difficulty breathing, seek urgent medical care immediately.To narrow down potential causes, we will need some more information.I understand you've been dealing with a cold, cough, and nasal blockage for the past two days.
