I did a little research on your condition and found out that you need IV infusion of Prednisone medication. You may have to take this med for life. Plus renal special diet.
Do exercises mild daily for 15-20 minutes and drink water as much as you can. This med will make you hungry and gain weight. Nothing else.
Clinical trials, you can participate.
Talk to your Nephrologist.
Good luck.
