Shingles and other skin rashes?

I have had shingles (or what they say is shingles) over 30 times. I use to get them once a year, but over the last year I have been sick almost every day. Aside from the patch on my cheek I usually get, I have random sores on my scalp, blisters on my chest and back and a patch under my nose. Acylcovir and Valtrex do not work. I have constant nerve paing and feel tired alot. Any ideas as to what this might be....I don't think it is shingles at this point, but not sure what it could be.
