I had a facet joint injection by one of the doctor's in the new Newton office. Hurt immediately after and then kept hurting(i.e., I didn't get any relief, and was made worse.) I had a facet injection in the past and had no pain, and only benefit, so I suspect something went wrong with this injection(e.g., doctor hit the joint or in some way aggravated things in low back). As always, your mileage may vary, but I wasn’t left with a feeling that this group was highly competent.
