<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, Ive been feeling very weak and nauseous lately. My legs also seem to be swelling up, and I seem to have a fever. On top of that, I have a cough and my stomach feels bloated. Could it be something serious?  <response>: Based on your symptoms, it sounds like you might be suffering from hemolytic anemia, a condition where your body destroys red blood cells faster than it can produce them. We will run some tests to confirm the diagnosis and start treatment right away.
