My 88 year old husband was told he had stage 3 CKD about a year ago (he seems to jump back and forth between a and b). At the same time when the knee jerk reflex was done there was no reaction on either knee. He has been treated for some years for BP, Thyroid, gout, mood problem, sleep problems and enlarged prostrate. He has extreme fatigue. Constant pain in the back in the kidney areas. Shortness of breath, pressure around the chest area. Blood pressure is normal with meds - however when he showers it drops to 90/41! He has to lay down. He also has purpura. Hasn't had a blood test since last November. I suspect he might be in Stage 4 or close to it. He does not want dyalisis or tests done at his age and health. I'm assuming the lack of reflex means he is suffering from peripheral neuropathy. Thank you. I hate seeing him suffer but not sure what to do. He only wants to eat waffles - sweet stuff and will eat fruit (which I give him often).
