Thanks. I've been going to physical therapy for the last 7 weeks. She has "unloaded" my T-spine and my L-spine. Today was my last visit. I haven't really seen an appreciable difference. We talked about a chiropractor. Her concern was that chiropractors like to "pop"your back. She has seen folks come in to her who have had their backs popped numerous times and the ligaments are so stretched that there is not to work with any more. After all this and the tingling/itching I feel in my right foot (especially), which sort of feels like the zingers I get but much more low grade, I am not convinced that the zingers are a manifestation of the PN, but for some reason they are positional. I don't know. I just don't know.
