I would tell him ya ya ya sure its for vasticulitis. U need to take a blood test for all std tests to see if he has anything else to. Aparantly he cheated or had it before u got married. Its also possible u had it before u got married & passed it onto him but mabye u dont know u have it. Its hard to say. But with him lying about the valtrex that dont look good on him either. If u have any questions give me a hollar.

Apparntly it is also prescribed for Shingles, also known as Herpes Zoster, which occurs when the Chickenpox virus becomes active again in someone who has previously had it.

Vasculitis is a broad term that encompasses many disorders that cause inflamation of the blood vessels

To what extent Shignles is associated with vasculitis, and whether or not his story holds up I cannot say.  I did find one article that reports a connection between Shignels and cerebral vasculitis.
