Just had mri after 4 months of low back pain. mri shows annular tear and mild disk bulge. about how long does this take to heal.

Whats the treatment?: You have an injury, what are you doing to fix it? It is possible the problem isn't disc pain and could be musculoskeletal pain in which case physical therapy and a home exercise program would be most beneficial. Most back pain heals within 3 months so if its not healing try something else, like anti inflammatories or pain management. Don't get discouraged and follow up with your doctor.
