Can shingles ras be internal?

Patient: Can the shingle rash be internal as in an ear or throat? Have not be diagnosed as of yet but have intense pain on the right side of my head,ear and neck. Right side of face at times feele numb. I am taking diclofenac sod ec 75 mg and hydrocodone-acetaminophen 5-500 but don’t seem to be getting any relief. I’m not even sure that my symptons are related to shingles. This has been going on for a week and a half and as of yet not external rash has appeared. I’m a bit frustrated the stabbing head and ear pain is getting to me, I really could use some relief as trying to function is difficult. Thank you.
