i believe i have shingles on my left foot, raised rash very itchy, itches more when i rubbed it,i ve been putting caladrly clear in it, it takes care of the itch a little, making it bearable. but it is contagious, like chicken pox, and do i need to stay clear of the family, wash the bedding( i ve been wearing one sock to bed, just in case..am I doing the right things?
