Healthy 33 year old female with almost constant lower back pain that usually radiates down one or both of my legs.... any suggestions on how to handle that?

If this is a chronic or recurring symptom, the first order of business is to make a diagnosis. Spinal arthritis, disc disorders inadequate spinal architecture are possibilities. For quickest workup& results, I favor being thoroughly evaluated at a spinal clinic where quick, appropriate testing will be done,results discussed and treatment options reviewed.
