I could be not be diagnosed for certain because I had no rash. The PHN is ongoing and extreamly dibilatating. A chiropractor has helped a great deal with manipulation and adjustment to the spinal area most affected such as upper back and upper abdomen. The pain is extreme and the chiropracratic manipulation only lasts a short while. Strong pain meds are out of the question. I wonder about a lidocain patch. Any help, I would appreciate it.
