It is possible that your persistent cough and cold symptoms after sinus endoscopic surgery are due to ongoing inflammation, incomplete resolution of sinus infection, or other underlying issues such as allergies or nasal polyps that were not fully addressed by surgery and medications.

🩺 Possible Reasons for Persistent Symptoms

• Residual or recurrent sinus infection despite antibiotics.
• Chronic inflammation or allergic rhinitis not fully controlled by current anti-allergy medications.
• Structural issues or nasal polyps that may require further evaluation.
• Non-sinus causes like asthma or other respiratory conditions contributing to cough.

🩺 Recommended Next Steps

• Follow up with your ENT (ear, nose, and throat) specialist for a thorough re-evaluation.
• Consider imaging studies like a CT scan of the sinuses to check for persistent disease.
• Review your current medications and their effectiveness with your doctor.
• Allergy testing or referral to an allergist may help if allergies are suspected.
• Avoid irritants such as smoke or strong odors that can worsen symptoms.

Consulting your ENT specialist again is important to identify the exact cause and adjust your treatment plan accordingly. If symptoms worsen or you develop new signs like high fever, severe facial pain, or vision changes, seek urgent medical care.To narrow down potential causes, we will need some more information.Could you please provide your age and gender?
