<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have a bad cough and difficulty in breathing due to green sticky sputum. Was given an antibiotic last time amoccillin? and this time doxicycline100 mg .my chest is easier but i still continue to cough up lots of green sputum .Will this get better of its own accord or is there a target specific antibiotic for this ?  <response>: Respected user, HiT hanks for using Chat Doctor.come have evaluated your query thoroughly. Vivid pathogens are responsible for the green sputum, common among them are streptococcus pneumonia and pseudocodes. Strongly recommended getting a culture of the sputum and take antibiotics according to that only. Hope to clarify your query. Welcome for further questions.
