Lisinopril Added Precaution, Kidney Function, Type 2 Diabetes, Ribcage, Cough

I was diagnosed with Type 2 Diabetes and went to an Endocrinologist and he put me on Lisinopril to protect my kidney function from any more damage from the Diabetes. He says it was minor damage that i had but taking the Lisinopril was an added precaution. I am 61 years old and have had no cough from this drug, but my ribcage and lung area, especially at night are in pain. I called him and he told me he doubts that the pain is from Lisinopril because it wasn't one of the usual side effects. I am to be off of it for a week to see.How is it that these doctors don't know that this is a side effect when there are people all over this website with the same complaints. I welcome any reply at ******
