Herpes zoster, colloquially known as shingles, is the reactivation of varicella zoster virus, leading to a crop of painful blisters over the area of a dermatome. It occurs very rarely in children and adults, but its incidence is high in the elderly (over 60), as well as in any age group of immunocompromised patients.
Do know that the marijuana you use would probably need to have THC in it. I do not think that plain CBD would be that helpful as it works best with inflammation.
Good luck.
