My back has been killing me lately. i do some heavy lifting at work but not often. ive already been to physical therapy and the exercises i was given havent been helping. the only thing that makes it feel better is to crack it. what else can i do?

Back pain that persists beyond 6 weeks should be evaluated with a lumbar x-ray, especially if you’ve followed physical therapy and have been complying with their exercise plans. If back pain causes radiation to the glutes, hamstrings, calves, or feet, there may be SI joint problems, disc herniation, disc slipping/fractures, or pinched nerves. Chiropractic services should be held until diagnosed.
