<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi Doctor, Ive been feeling quite unwell for the past few days. I have symptoms of flu-like syndrome and tongue lesions. What could be the reason for it?  <response>: It sounds like you might have a parathyroid adenoma. This is a non-cancerous growth on one of your parathyroid glands that can cause a range of symptoms, including those you are experiencing. I would recommend running some tests to confirm the diagnosis.
