<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, Ive been experiencing loss of sensation, coryza, and nausea for a while now. What could be the problem?  <response>: Based on your symptoms, its possible that you have a pituitary adenoma. This is a tumor that grows on the pituitary gland, which can cause a variety of symptoms including those youve described. Well need to run some tests to confirm the diagnosis.
