<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I have noticed some skin lesions on my arm and I am also experiencing fluid retention. Additionally, I have a mass in my neck and my throat is swollen. What could be the reason behind these symptoms?  <response>: Based on the symptoms youve described, it is possible that you are experiencing lymphedema. This condition occurs when there is a buildup of fluids in your lymphatic system, usually resulting in swelling of an arm or a leg. The skin lesions you mentioned and the mass in your neck are also common symptoms of this disease. I suggest we conduct further tests to confirm the diagnosis.
