<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, Ive been experiencing swelling in my legs and feet for the past few weeks. Its been really uncomfortable, and Ive been having trouble breathing at times. I think I might have fluid overload.  <response>: Im sorry to hear that. Based on your symptoms, well need to run some tests. The first one well do is a complete blood count CBC and some hematologic tests. Well also need to perform a radiographic imaging procedure and an electrocardiogram. Additionally, well need to do a plain x-ray, measure your glucose levels, and perform some kidney function tests.
