What could cause mid back pain on left side when you turn a certain way?

Answer 1

There are many things that could cause pain. The first thing to do is to determine what the source of the pain is--is it osteopathic, is it circulatory, is it neural, is it muscular, or is it epidermal? If the pain is osteopathic, it could be caused by stress fractures in the vertebrae, something that needs immediate medical attention. If it is circulatory, you may have a circulatory problem, which needs medical attention, or you may have a bruise. If it is neural, it may simply be a pinched nerve. If it is muscular, it could be a strain or a pull, in which case, simply because of its location it may be prudent to have it examined by a practitioner. If it is epidermal, it should be very obvious what is causing the pain, as there would be a noticeable rash or abrasion. The most likely cause is either bad posture, as a result from non-ergonomic chairs or a bed that is not soft enough, or it could be stress-induced. In any scenario, the best you can do for it if it is nothing to worry about (that is, if it is not anything that resembles the problems I described above) is to simply have a good night's sleep, possibly on a softer mattress, and try to relax more.
