Protein in urine symptoms and conditions

MY HUSBAND WAS RETAINING ALOT OF WATER IN HIS LEGS AND VERY WEAK. THE DOCTOR HAD DONE A NUMBER OF TESTS ON HIM TO FIND OUT THAT HE HAS NEPHRITIS AND WAS LOSING 8,500 MG OF PROTEIN IN URINE A DAY (NORMAL IS 100-200 MG PER DAY), AND COLESTEROL WAS AT 400. HE WAS PUT ON PREDNIZONE AND ALSO HAD A KIDNEY BIOPSY. WE WERE MARRIED 1 WEEK PROIR TO HIM BEING PUT ON PREDNIZONE AND IT HAS BEEN PRETTY TOUGH TO DEAL WITH. HE WOULD COMPLAIN OF ALL THE SAME SYMPTONS, WEAKNESS, BACK PAIN, NAUSEA, BLACK OUTS, MAJOR WEIGHT GAIN, AND CRAMPS THAT WOULD KNOCK HIM ON THE GROUND. I NEVER REALIZED PREDNIZONE WAS SO BAD. I FEEL ALOT OF GUILT BECAUSE I WOULD SAY OH, IT CAN'T BE THAT BAD. I FEEL HORRIBLE NOW READING ALL OF THE OTHER COMPLAINTS. HE HAS ABOUT 1 MONTH TO GO WITH 60 MG OF PREDNIZONE A DAY AND WATER PILLS.
