I'm sorry you have a situation that leads you here, though.

If what your are describing is nerve-based pain, then NSAID pain relievers are not likely to be much good. There are other meds--anti-convulsants and antidepressants among them--that are usually more effective.

It is possible to have shingles-based neuralgia without the rash--this may be determinable through a blood titer.

In any case, come on over to our Peripheral Neuropathy forum:

Lots of empathy and knowledge over there.
