Don’t have a lot to share, but I had poor renal function looking like the beginning of ESRD, but it was because I had an obstruction with a stone. When it did pass it was resolved. I passed the stone on my own at home. As far as a PCP I know my last one took some getting used to. He later felt like great support and he left. I was so sad that he left. I live in a place where it is a long wait for a new one. I don’t have that. I would say to get on some wait lists if you do want one. Always trust your gut on things. Just because someone says he is good he might or might not be a good match for you. Only you were in the appointment and only you know best.
