Daughter’s Scoliosis Treatment Discontinued Prematurely - Legal Recourse?

Certainly! Here's a clearer rewording of the text:

My daughter was diagnosed with scoliosis around five years ago and was treated by a pediatric orthopedic specialist for a couple of years. She wore a brace to prevent the curve in her spine from worsening. Around a year ago she was released from their care because her growth plates had closed. Scoliosis curves worsen through growth so with her growth plates closed we were told that she no longer needed to wear the brace at. Even being told that we could burn it if we wanted to. So we thought the treatment was over.

Recently, she has been experiencing severe back pain, and upon consulting another orthopedic doctor, we discovered that her scoliosis curve had progressed significantly from the degree it was when her previous doctors car ended. The new doctor emphasized through X-rays that her growth plates were still open and not even close to closing, indicating that she was still growing and at risk of the curve worsening to a point that will require surgery. Now, she needs to wear a new brace almost full time just to give the prospect to avoid surgery. She only has five degrees left before surgery is required to be exact.

I'm wondering if there's any legal recourse against her previous doctors for prematurely ending her treatment, which may have led to her current situation. It feels like if they hadn't discharged her, we wouldn't be facing this risk of surgery now.
