I Am 20 Years Old And Have Been Having Back

I am 20 years old and have been having back pain for a year now. It is my upper back on my right side kind of where my shoulder blade is. I have been going to a chiropractor for about 6 months now but I still have a lot of pain. I used to run 3 miles every day and now I cannot even go a mile without too much pain. I cannot play volleyball anymore either because jumping hurts it.
