Why would my spine hurt to touch in just one area? it hurts to touch one of my thoracic vertebrae. no history of trauma.

Wait And See: One little isolated spot of thoracic vertebral tenderness is hard to figure out without an in-person exam.In your age group it's usually due to a bump or strain,but you say that's not the case.If you said you'd had an infection(even of a tooth)or a fever,then I'd be a bit more concerned and suggest someone take a look at it if it persisted over two weeks or so.If you use IV drugs,get to an ER now.
