I just had a hip replacement 10/11/16 and had no rash, but by 10/17/16 II had a large cluster of burning ,oozing red blisters which my wife noticed all over the middle/lower back. I did have chicken pox as a kid and we have had recently had some very stressful problems with one of our 43 year old kids. I'm 67 . My wife is also 67 and has never had chickenpox, she also has had 3 smallpox vaccines that never took even as a young adult and she was exposed to our kid's chickenpox and taught elementary school with students who had chicken pox. Should she be worried about getting pox and should I take a product like Zostavax? Please Help! Lou
