I am 42 years old been diagnosed with PKD for almost 3 years now. Kidney function is 20%. I went to Dr today but saw his PA. Less just say when I left she had me crying. She asked was I tired? YES all the time. She asked was I nauseous or vomiting? YES most of time. She asked did I have back pain? I said YES and it has this pulsating feeling to it. She then told me I must be depressed cause ppl with 20% kidney function don't feel as bad as I do?? She never her of back pain like that. I really felt like I was crazy by end. Am I only person that feels this bad?? Is this in my head?? I feel like I'm losing my mind. I am not depressed at all. I've also gained about 50lbs that I can't get off?? Any advice would be greatly appreciated.
