It is very reassuring that you have no fever, and your oxygen level (97%) and pulse (75) are completely normal. At 73, it is wise to be cautious, but a mild viral cold and cough often take 7 to 10 days to resolve, so three days without major improvement is quite common. Since you are already taking paracetamol and Montek LC (montelukast/levocetirizine), continue focusing on rest, warm fluids, and steam inhalation to soothe your throat. Please monitor your symptoms. If you develop any shortness of breath, chest pain, or a new fever, please consult your doctor promptly for a physical evaluation.

The persistent sensation in your throat and ear irritation are closely connected because they share the same nerve pathways. This is often caused by acid reflux (addressed by your PANSEC L) or environmental allergies (addressed by your MONTEK LC). Traditional remedies like neem offer limited relief for these internal issues. Please continue your prescribed medications as they target these root causes. I highly recommend consulting an ENT specialist for a simple physical examination of your throat and ears to help you find complete comfort.

Montek LC, a combination of montelukast and levocetirizine, is generally very safe for long-term use under medical supervision. It is highly uncommon for this medication to cause harm to your liver, kidneys, or overall organ health. Occasionally, doctors may recommend routine blood tests just to monitor your overall wellness during prolonged use. The key is to stay in touch with your doctor and let them know if you experience any unusual mood changes or sleep disturbances.

Since you don't have a cough, this mucus is likely pooling from your sinuses. Since antihistamines only provided temporary relief, you might find saline nasal rinses helpful to physically flush out the secretions. Additionally, a generic intranasal corticosteroid spray, like fluticasone, can help reduce localized inflammation in your nasal passages. A generic mucolytic like guaifenesin can also thin the mucus, making it easier to clear. Please stay well-hydrated, and consult a healthcare professional to tailor these options to your needs.

Please do not give Montek LC syrup to your 15-month-old daughter without consulting her pediatrician first. This medication contains a combination of levocetirizine and montelukast, which requires precise, weight-based dosing and is generally not recommended for self-medication in infants. To help her feel better safely, you can use saline nasal drops to ease her congestion. Please consult her doctor for a proper evaluation and safe treatment plan.

Typically, sinus surgery is considered only after comprehensive medical treatments have been tried and have not provided relief. Since you have only tried Montek LC (montelukast and levocetirizine), there are still several highly effective, non-surgical options available. These often include saline nasal rinses, prescription nasal steroid sprays, and sometimes targeted antibiotics if a bacterial infection is present. I highly recommend discussing these conservative medical treatments with an ear, nose, and throat specialist before considering any surgical procedures.
