I wa s diagnosed with CIDP Feb 2006 and immediately went on 5 ivig’s every 4 weeks for two years. Then we went to 3 every 4 weeks til Feb 2010. Went off for a year I am now back on 5 every 4 weeks to be evaluated in 6 months.The doctor also prescribed Tegretol both of these treatments seem to be helping the burning cold in my hands. In addition I have been diagnosed with pulmonary hypertension for which I am being treated with blood pressure meds, Lasix and nighttime oxygen. Hang in there and check out Tegretol , it is inexpensive and seems to be effective.
