Amanda  <response>: Hello! Welcome to Ask A Doctor service! Regarding your concern, I would explain that your symptoms could be related to an infection. For this reason, I would recommend consulting with your attending physician for a physical exam and some tests: -a chest X-ray study-complete blood count, PCR, ESR for inflammation- blood bacterial culture- a urine analysis-urine bacterial culture. Further tests may be needed to investigate for the type of infection. Hope to have been helpful! Wishing good health,
