How old is your partner and do you know where his shingles showed up? Do you know if he has had shingles before? Do you have any idea about when his last sexual encounter with another person happened?
It’s difficult to answer the rest of your questions without knowing more about the questions that I asked. Shingles is not normally a problem of younger people, though it can happen. My concern is that sometimes clinicians mistake herpes for shingles and I’m trying to sort out if that might have happened here.
How long ago was the encounter with him that you describe?
It will not help me to get a western blot unless it has been 16 weeks since his last encounter with someone that has unknown test results. When was your last sexual encounter with anyone?
