[|Human|] I have an upper respiratory infection that seems to be lingering. I have been taking amoxicillin, 500mg. for 4 days. I do feel better but still have a lot of congestion. The nasal mucus has gone from being quite thin and clear to much thicker and greenish/yellow. I am concerned I am not getting rid of the infection. What do you think?
[|AI|]  Respected user, hi I evaluated your query thoroughly.* Usually upper respiratory tract infections are airborne through atmospheric bacteria / virus / pollen / tiny dust particles.* Recovery part depends upon the causative organisms, host immune response, type of treatment, associated comorbid conditions etc.* Better to get consulting with your doctor to get early rid of infection & congestion. Hope this clears your doubts. Thanks for using Chat Doctor & keeping trust in our medical services. Wishing you fast and speedy recovery. Welcome for any further issues. Regards dear take care.
