[|Human|] I have had a cold for over 3 weeks now and still have nose congestion along with a good hefty cough (which for me means the end of a cold and loosening up) but I still cant breath what over the counter medicine can I use besides Alavert D-12 and Alka Seltzer Plus?
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. By your history and description, possibility of post infectious bronchitis is more likely. Bronchitis causes bronchospasm and this in turn causes cough, expectoration and breathing difficulty. So consult pulmonologist and get done clinical examination of respiratory system and PFT (Pulmonary Function Test). PFT will not only diagnose bronchitis, but it will also tell you about severity of the disease and treatment is based on severity only. You will improve with inhaled bronchodilators (formoterol or albuterol) and inhaled corticosteroid (ICS) (budesonide or fluticasone). Don't worry, you will be alright. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
