Hi, I m 17 and for the past year or so I ve been getting sharp, painful sensations of the pins and needles sort under/behind my ribs or in varying spots throughout my spine. I ve never had surgery and I am up and about often, and these sharp pains occur at fairly spaced out intervals for minutes at a time, but often enough that it is not an isolated pinched nerve or a one-time thing. What confuses me is that I could been relaxed and standing still and then move only the slightest bit, and the sharp pain will erupt. If it s in the ribs, it will on occasion spread wider throughout my chest area, which, for obvious reasons, kind of freaks me out and makes me question whether it s a bone or organ related issue.
