<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, Ive been feeling very tired lately, and Ive been experiencing congestion in my chest. Ive also been having pain in my testicles and a runny nose. What could be wrong with me?  <response>: Based on the symptoms youve mentioned, its possible that you have Thalassemia. Its a genetic blood disorder that affects the production of hemoglobin in your body, which can cause fatigue and congestion in the chest. Pain in the testicles and coryza are less common symptoms, but they can be present in some cases. I recommend you to take some blood tests to confirm the diagnosis.
