I've had the tender back the last three weeks. The skin is tinder very very light swelling in areas upper back only in the skin tissue I have had absolutely no injuries stresses or anything muscular in the way of bodily injury. . No scratch no sores no lesions most of the skin looks perfectly normal except for slight red tinges in small areas.. In the last four months I have had shingles vaccination. I have had the chickenpox. Or smallpox whichever thiat is the problem.
Could this be small flareup of shingles? Or are there other more serious problems but I should be looking to?
