Hi, your story sounds so, so similar to mine. My daughter, who is also 9, has been dealing with this since April of this year. We followed similar pattern, Sever's (no injury trigger, though she was doing an after school running program), ice, Advil, rest, didn't get better. Finally got an MRI and a Dr with a diagnosis of CRPS. We have found a PT that knows about CRPS which is really great, but so far PT isn't helping her pain. She hasn't tried any medication yet.
