My 89 yr old grandmother was diagnosed with "the worst cast of shingles I have ever seen" by her gp last year. While the original outbreak has healed she is still have frequent pain and itching in the same location (scalp, face and eye lid). Other than pain meds are there any other treatments that she could benefit from at this point? She lives in Washington state, are there any specialists there that she should consider going to?
Thank you.
