hi rider, i m physical therapist running my clinic in india, i think in your case, lumbar traction with foot in 90 degrees, with 1/3 of body weight, intermittent, for 6,7 days for a period of 20 min. daily would help, see traction helps in bringing back the prolapsed disk to its original form, or you can also look for distraction therapy, along with that spinal anterior posterior glides forthe affected disk wud help her, all this corticosteroids injection are not the treatment for this, they are just the temporary thing, its good not to go for surgery at this point
