Hello,
As per your clinical history is concerned, please follow like this:
1) Do a clinical examination by your Doctor and to know exact cause do few investigations like [CBC with differential, nasal
endoscopy, and CT scan].
2) Do use
nasal spray [Oxymetazoline] and take OTC decongestants.
3) Use the nasal saline spray and discuss with your Doctor about a course of antibiotics like [Doxycycline].
Do follow lifestyle modifications like this:
1) Avoid upper respiratory infections. Minimize contact with people who have colds. Wash your hands frequently with soap and water, especially before your meals.
2) Carefully manage your allergies. Work with your doctor to keep symptoms under control.
3) Try to avoid cigarette smoke and polluted air. Tobacco smoke and other pollutants can irritate and inflame your lungs and nasal passages.
4) Use a humidifier at bedtime.
Hope I have answered your query. Let me know if I can assist you further.
