<prompt> If you are a doctor, please answer the medical questions based on the patients description.i had chest pain on left side. X ray was showing some infection. I took antibiotics with consultation of family doctor. Now I am ok with pain. But xray is not very clean, however there is an improvement. Is it required to do any more treatments?  <response>: Thanks for your question on Chat Doctor. I can understand your concern. By your history and description, possibility of pneumonia lung infection is more likely. In pneumonia, symptoms appear first then appears infiltration on chest x-ray. Similarly, when we start antibiotics, symptoms disappear first then x-ray infiltrates. Since your symptoms are gone, no need to worry about x-ray infiltrates. It will take time 2-3 weeks for complete resolution of infiltrates. So get done repeat chest x-ray after 3 weeks. It will mostly become normal. If infiltrates are seen even after 3 weeks then get done CT thorax. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
