Muscle pain

I fell down the stairs this summer when it was raining and hurt my shoulder. The ER did an x-ray, and determined nothing was broken. It is now almost 2019, and the shoulder is still pain filled, and causes restless nights. I don’t know what to do. I’ve gone to chiropractor for adjustment, as well as getting a massage. Also take NSAIDS such as Tylenol or Advil. Any advice?
