Herpes Zoster Ophthalmicus Discovered During Pain Consult Possibly Complicated With Dural Sinus Thrombosis and Refractory Headache Managed With Ketamine: A Case Report.

Pain is a common symptom associated with shingles and may precede the onset of the characteristic rash. In the context of herpes zoster ophthalmicus, pain can manifest with severe headaches, posing challenges due to other potentially life-threatening conditions such as stroke and intracranial hypertension. In this report, we present the case of a 51-year-old male with severe headache and imaging findings of dural sinus thrombosis. He was later diagnosed with herpes zoster ophthalmicus and required aggressive inpatient management of neuropathic pain. Despite appropriate treatment, acute herpes zoster can progress to post-herpetic neuralgia, requiring long-term pain management.
