Can i use topical benzocaine on shingles?

Best treatment is: Oral antiviral meds: shorten course of infection & help prevent nerve pain of untreated shingles. Topical creams containing capsaicin may provide some relief from pain, but this hot-pepper derivative may "burn" or irritate the skin of some people (& should be used with caution to prevent getting in eyes). Topical preps with Benzocaine may help.
