<s>[INST] I have had a chesty cough for 8 weeks I ve tried benlyn cough mixture various cough tablets. Black magic cough mixture and antibiotics I still feel very ill and I am coughing so much I go dizzy I still have a very chesty cough and don t know what to do [/INST] Thanks for your question on Chat Doctor. I can understand your concern. You are having chronic chesty cough (cough with expectoration) since 2 months which is not improved by routine OTC (over the counter) Chat Doctor.  So better to consult pulmonologist and get done clinical examination of respiratory system, chest x-ray and PFT (Pulmonary Function Test) to rule out lung infection and bronchitis. You may need higher antibiotics, inhaled bronchodilators (formoterol or albuterol) and N acetyl cysteine (NAC) depending on the reports.Don't worry, you will be alright. First diagnose and then start appropriate treatment. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
