Sudden strange upper back pain?

Hi again, everyone! Here i come again to ask about yet another symptom and searching for reassurance. Been having 2 days with a sudden upper back pain. I don't usually suffer this. Maybe once or twice a year and goes away within a few hours/days and most of the time it is for having had a strong physical activity or been sitting in a bad position for hours. ¿Could it be the benzo? ¿Should i go to a doctor? Thanks in advance!
