... originally treated with a high dose of prednisone (60 mg 2x/day) and IVIG infusion treatments. I had a bone marrow biopsy which led to internally bleeding into my backside for three days. This, in turn, led to hospitalization with round the clock blood and platelet infusions. I had the splenectomy and then was put on NPlate. Did the Rituxan treatment and then was put on Promacta in April 2009. Promacta seemed to do the trick. I was in remission (no meds, level checks every 3 mos) for roughly a year and a half. Caught pneumonia in February 2012 - retriggered the "virus". Promacta not doing the trick this time. I am back on IVIG therapy. This time around, I experienced wicked side effects (severe headache from front to base) and body stiffness starting at the neck (flu like but much more severe). Any body else experienced this?
