Answer
  Your level of pain, arthritis, and bulging disc indicates that you should see a PT who specializes in both prenatal/postpartum issues and spine/disc problems. Get a referral from you doctor. A steroid injection will reduce swelling and pain, but treats your symptoms, not the underlying cause(s) of your condition. Also, have you discussed how steroids will or will not effect your breast milk and new baby?
