I'm a bit concerned about this white spot that showed up on my chest x-ray about 25 days ago. It was on my left upper lobe lung area. My doctor had me on antibioticsclindamycin and moxifloxacinfor three weeks, and the spot seems to be getting smaller and less noticeable. I'm wondering if I should keep taking the antibiotics until the spot is completely gone. The doctor said it was a patch from a previous infection. Does this mean it's benign since it's not getting bigger, just shrinking?
