What Is The Treatment For Severe Back Pain?

out of no where one day i had a pain in my lower back.thought was my office chair so went and got another one. couple days later pain was so bad i couldn t do anything but lay down. it got better to the point could return to work ( i work from home sit in a chair 40 hours a week) don t workout as much as i should but i have no idea how or where this pain came from. well i went to chiropractor. he said was very swelled and my hip is out of alignment he did some stretching it popped and it did get better but still not back to normal. i start to worry because been over a month now and i still cannot run without excruciating pain. not sure if i should go see doctor go back to chiropractor or just give it more time. i can sit and do my job just very irritating. like right now not alot of pain at all just when i move in a angle or run its just not right.
