Temperature sensations

I’m in my 4th year of ivigs, two every 4 weeks. for the treatment of CIDP. My hand sensations are improving,but they feel at times like they are on fire,especially after using them alot.My legs are “numb” from the knees down,but I am starting to feel temp changes. I still have drop foot on the right side, but I am improving. Hang in there ,but don’t overdo ,which is a fine line.
