Thanks for reaching out, its funny I even saw the post, I have had the vasculitis under control for awhile. Had four of the 6 treatments. They weren't too terrible. I was in bed with mild flu like aches and mild nausea which the doctor had prescribed meds for, but I couldn't eat much of anything. I had baked potatoes and pretzel sticks over those weekends. But hydrated myself like crazy like she said. It was important to flush the bladder so I did. I had a headache with each treatment that got worse each time, so after the fourth treatment I told her I couldn't handle the headache at home if it was going to be worse as I am a single mom. So we tried the oral cytoxan, and I still had bad headaches. but because the inflammation rate came down, which is how they monitored the effect of treatments we decided to stop, and control the symptoms. I am only now coming off prednisone. And as I write this, have had the electrical shock pains in my back, and have bad pains in my calves, my legs gave out this weekend, I could on, but all here understand, so I'm not sure what part of my disease is acting up as I am still not diagnosed with another auto immune disease yet, I am one of those in limbo land, but not feeling good, so it may be the vasculitis again, feels something like it. Hope your friend gets some relief, as for information it is far and few, I never did find much.
