Hello,
I suggest you to get an immediate evaluation done from a doctor as stiff neck may be a sign of central nervous system involvement. Any sign of shingles like headache, stiff neck, dizziness, weakness, hearing loss, or changes in your thinking and reasoning abilities should be reported to a doctor.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
