I would specifically like to speak to a nephrologist. My husband had PKD; he is now ESRD. His kidneys were removed last January 28, 2013 at Johns Hopkins in Baltimore. They weighed an astonishing 49 pounds. He was in JH for 77 days post-op; 16 days in the ICU. He is on dialysis at a facility close to our home -- and was doing well. However, a week ago he passed out during dialysis -- and felt sick and dizzy yesterday when I picked him up (I have never allowed him to drive after dialysis). He also says he experiences a burning sensation at intervals all around his waist. His nephrologist (who visits him weekly at the dialysis facility) does not have an explanation for the burning sensation or the more recent difficulties he is experiencing. He is now on the Active list for a transplant at JH. My concern is what could be causing him to experience such difficulty recently during and after dialysis. Any suggestions -- I have asked that he be given some water 15-20 minutes prior to the end of his session (total of 3 1/2 hours Monday, Wednesday and Friday.) Thanks.
