The herpes infection can involve other nerves in the area of the primary infection - for example the trigeminal nerve (shingles over the eye/forehead), facial nerve (shingles around the ear and a face droop), and vestibular nerve (dizzuness and vertigo), and auditory nerve (hearing loss). Due to nerve inflammation, it may take weeks to months for the symptoms to resolve. An MRI may show contrast enhancement in the nerves affected. An MRI and MRA would be worth doing to exclude a mass lesion, especially in the setting of a droopy eyelid which may imply 'Horners syndrome' - a problem with the sympathetic nerve supply of the eye - common causes include a neck artery dissection (tear) or a masss lesion in the neck. Treamtent for a herpetic 'shingles' infection is with acyclovir and steroids but is only shown to helpful in the first 2-3 weeks of the infection. After that the nerve just have ot recover by themselves over time.
