zoster always connected to hiv positive I am only 26 and came down with a case of herpes zoster. i heard that there can be other causes such as the fact that i was under high stress at work, on my period when the zoster broke out on my back, also sunbathing, and i had 2 root canals done all in the time frame that this broke out, is it true that these could have been factors? or am i just wishful thinking that i may still be healthy?
