<s>[INST] Hi , This is Naga  age 29. I have cold for almost 15 days and my left nostril is continously blocked.  I cant breathe easily when i am in A/C. I have a sore throat  as well. From childhood , i am immune to cold.  I stay away from cool drinks, ice creams as i get effected with cold immediately. [/INST] Hello! you seem to have Allergic rhinitis with respiratory tract (throat) infection . I would suggest you take a short course of Tab. Montek LC,an antibiotic either Tab . Amoxyclav or Tab. Azithromycin , Tab. pantoprazole.   Use   Budanase AQ nasal spray .Do gargling with betadine gargle solution four times daily and do regular warm saline gargle. Drink only warm fluids. Keep away from cold and dust . Hope this helps.  Do drop in your valuable feedback. </s>
