Hello All, I just will have my 21 infusion on the 1st of November. After my 19th infusion I developed a rash that looks like 6 spots each a little smaller than the size of an easer of a pencil. They look like little blisters, burn sort of but don't itch. They do not go away but they are starting to spread slowly. I am JCV positive after my 6th infusion blood work. Any help, or suggestions would help. Thanks All. Lisa
