<s>[INST] Hello, I am generally in very good health but caught the circulating cold this month. I tend to get through the viral phase of a cold quite well, but the tail end can hang on for a considerable amount of time: thick, yellow-green mucous that won t seem to stop producing. Inflamed nostrils and sinuses; and - because I had my tonsils out as a child - post nasal drip that collects quickly in my lungs. I m careful about my diet (minimal dairy, hardly any sugar, no gluten); manage stress well; take supplements - multi, probiotics, oregano oil (currently); sleep well. The symptoms are quite acute and inconvenient, and I wonder if you have any suggestions - lifestyle, dietary, or medical - that I can implement, so that I can kick this. Thank you! [/INST] Hello, Welcome to Chat Doctor, Symptoms are suggestive of lower respiratory tract infection of bacterial origin. This infection is leading to other symptoms of inflamed nostrils and sinuses. The green color mucus is evident of bacterial infection. I would have suggested1. Steam inhalation2. Broad spectrum antibiotics3. AntihistaminesMedicines should be taken after consulting your doctor. Thank you. </s>
