Four years ago an MRI of my spine came up abnormal and I was told my pain was from stenosis (this was before I was diagnosed with CRPS). The recommended treatment was steroid epidurals and I tried two but did not have any relief from the injection. However, I tried the out patient ketamine and found each treatment gave me 3-4 days of solid relief so maybe the epidural treatment will work for your daughter especially with a buldging disc.
