The fatigue came first when I went through my last flare. I knew something was wrong. I was working out 4 times a week and feeling just fine. One day, I woke up, and all of my energy was gone. The cramping/nausea came later. I tried to tell the doctor how tired I was, but he blamed it on the fact that I have a year and a half old baby to run after all day. They just don't get it sometimes!
Since my flare got under control, I've been feeling so different. I have tons of energy, but I think it's the prednisone. It gives me so much energy that I can't sleep at night. I'm scared that when I get off the prednisone, I'll start feeling sluggish again.
I've heard that B-12 shots may help. I wish I had more advice!
