Hello Dr. My name is Jason,  I had my right kidney removed in 1999. I have too much body heat, sometimes I feel blood rushing into my head, this happens only at knight while asleep. my body becomes very sweaty and humid. I live in a very dry climate in South Africa.
Hi Jason, These symptoms could suggest anemia related to kidney disease as you have single kidney. I would advise you to get in touch with local hospital for evaluation in detail
