I am having nerve pain and intense itching over the thoracic region of my spine mostly on the left side. It is causing painful trigger points (knotted muscles) in the same area. I was referred to physical therapy for thoracic spine strengthening and deep tissue massage twice a week and I exercise at home twice daily. This treatment after 6 weeks appears to be a band aide approach to the problem with minimal relief. I had shingles in 1980 and I wonder if this skin pain is due to a reoccurrence of the shingles (without rash)?
