We have had regular tests on everything you can imagine. Blood work always done, on time and reported to the right doctors. Absolutly NO symtoms or discussion of renal failure all these years. Out of the blue, we are told he has 4th stage renal failure and has to go to a specialist. NO symtoms what so ever. I am lost and confused on this one and do I need to let the VA know? Do we need to file another claim? OK, folks, I need your help again.
