I've got shingles. Yuck. It is possible for me to accidentally spread it to other parts of my own body? If the virus is on my fingers (from touching the blisters, I suppose) and I touch my eye, could it spread to my eye and make me go blind? If I touch my genitals, could I give myself genital herpes? These sound like really stupid questions written down but I don't want to take any chances.
