<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, Ive been feeling extremely tired lately and I dont seem to be growing at all. My legs also feel weak and swollen.  <response>: Based on your symptoms, it seems like you may have aplastic anemia. This is a rare condition where your bone marrow doesnt produce enough new cells, causing fatigue, lack of growth, leg weakness and fluid retention. We??l need to do some tests to confirm.
