modern dancer with knee pain

[Guest guest]

I am a modern dancer who was diagnosed with CP

back in February. The doctor did NOT take an MRI, only

an x-ray. She sent me to a PT who gave me exercises

that helped a lot-- leg raises with weights,

stretches, strengthening of the inner thighs etc. My knees

were feeling much better while, but now I'm

experiencing the same pain again. Curtailing my dance

activities is not a desirable option. I do my exercises

about 4 times a week and I ice afterwards on days when

I am particularly sore. Any advice?
