<s>[INST] hi doctor about three years ago I had scans on my kidneys and I was told I had poly on my kidneys which I was told at the time were benign or harmless and I was discharged suddenly this week I am getting a strong itchy feeling under my rib cage both front and back do you think I should see my doctor or do you think it will eventually go away [/INST] Hello, In most cases only close followup is required. You can opt for three monthly follow up with periodic ultrasound scan and renal function test(RFT). If there is no HUN(HY Chat Doctor.  Treatment is only required when renal function worsen. The pain may not be associated with your cystic disease, and you can take over the counter available analgesics like paracetamol for pain relief. Hope I have answered your query. Let me know if I can assist you further. Take care  </s>
