I'm sorry to hear that you're still feeling unwell after several days. A cough and blocked nose lasting 4-5 days can be due to various causes, including viral infections like the common cold or bacterial infections. Novamox 250 is an antibiotic, which suggests your physician may have suspected a bacterial infection, and Lax is likely for symptom relief.

Since you are not improving, here are some important steps to consider:

• Follow-up with your doctor: It's important to revisit your physician or consult an ear, nose, and throat (ENT) specialist to reassess your condition. Persistent symptoms might require further evaluation or a different treatment approach.
• Symptom monitoring: Watch for any worsening symptoms such as high fever, difficulty breathing, severe headache, or facial pain, which would require urgent medical attention.
• Supportive care: Continue to rest, stay hydrated, and use saline nasal sprays or steam inhalation to relieve nasal congestion.
• Avoid self-medicating: Do not start or stop any medications without professional advice.

If symptoms persist beyond 10 days or worsen, it could indicate complications like sinusitis or another infection needing targeted treatment.

Please consult your doctor or an ENT specialist promptly for a thorough evaluation and appropriate management. If you experience severe symptoms, seek emergency care immediately.To narrow down potential causes, we will need some more information.I understand you've been dealing with a cough and blocked nose for 4-5 days and haven't improved with the prescribed medications.
