What exercise can i do to help mid side back pain? or other help? - mid-back pain more condition_treatment

I had (back pain for about half of my time from the left side) for the years (5-10?). After half an hour or I have to so.What do about it? I do it, therefore, support for the use of prescription painkillers (Advil, etc.) and the lower back, if I ever had to endure for long. Go to a doctor is not an option, I had no insurance or money for that matter. Thanks for the help.
