Your symptoms suggest a nasal allergy, which can be triggered by cold exposure or allergens. Avoid known triggers, dry your hair quickly after washing, and protect yourself from cold air. Steam inhalation and maintaining good nasal hygiene may help reduce symptoms. Consult a doctor for proper evaluation and long-term management.

What you are experiencing is actually quite common. Your Allegra nasal spray works to reduce inflammation and control allergy symptoms, but it does not cure the underlying allergy itself. Once the medication left your system after ten days, the swelling and mucus returned, especially if you are still exposed to environmental triggers. I highly recommend consulting your doctor. They can safely guide you on a longer-term management plan to keep your airways clear and help you breathe comfortably.

Snoring is very common and usually occurs when the airway is partially blocked during sleep. Simple lifestyle changes often help significantly: try sleeping on your side, maintaining a healthy weight, and avoiding alcohol before bed. If nasal congestion is the cause, a generic nasal corticosteroid spray like fluticasone or saline rinses can reduce swelling. Because persistent snoring can sometimes indicate a condition called obstructive sleep apnea, it is best to consult a doctor. They can evaluate you and discuss tailored options, such as custom oral appliances, to help you get a safe and restful night's sleep.

To relieve a runny nose caused by pollen allergies, you can use over-the-counter options. Non-drowsy oral antihistamines, such as cetirizine, loratadine, or fexofenadine, work well by blocking the allergic response. For more direct relief, steroid nasal sprays like fluticasone propionate are highly effective at reducing inflammation and stopping nasal discharge. Additionally, using a simple saline nasal spray can help flush out pollen and soothe your nasal passages. I suggest starting with a daily antihistamine or nasal spray. If your symptoms persist or if you have other health conditions, please consult a healthcare professional for personalized advice.

To help your child breathe easier, you can use saline nasal drops or sprays before bedtime to clear mucus safely. For adenoid-related congestion, a paediatrician may prescribe steroid nasal sprays, such as fluticasone or mometasone, which help reduce swelling in the adenoids and nasal passages over time. Please avoid over-the-counter decongestant drops (like oxymetazoline) for more than three days, as they can cause rebound congestion. Using a cool-mist humidifier in their room can also keep airways moist. Since adenoid issues require careful monitoring, please consult your paediatrician or an ENT specialist for a personalised treatment plan.
