Thank you for your reply Ginger. I think the problem with my not getting a heads up before how is that it's been 2 years since my health clinic had a doctor they have been relying on the head of practice, which was never seen, and two nurse practitioners. I'm afraid I don't know what a eGFR level is, I go over my notes on the clinic portal and see if I can find it.
My shock is because after 5 years of PMR I was feeling great and thought I was in great health, which apart from the kidneys I am my test results from my physical were almost perfect. I'm still having something of a hard time coming to terms with it. It also changes my long range plans. I have an appointment with my new doctor in three months and I will go over getting a nephrologist then, but because of our rural nature it's hard to attract good doctors so there may not be one close enough. In the mean time I will be adjusting my diet and drinking a lot of water.
