<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, Ive been experiencing low back pain, skin growth, and frequent urination. What do you think is wrong with me?  <response>: Based on your symptoms, its possible that you have Polycystic Kidney Disease. This condition causes cysts to form in your kidneys, and in some cases, it can also cause skin growths and urinary problems. I would recommend further tests to confirm the diagnosis.
