. There may be clustered vesicles with redness,itching and burning. The lesions may be in zone. You consult dermatologist
. He may prescribe you acyclovir in proper dose for 2 to 3 weeks along with analgesic. Steroids may be taken in tappering dose to prevent postherpetic neuralgia. Silver sulfadiazine
cream may be applied on the lesions
You may be alright in few weeks.
