My son walks on his tip toes. He has had an MRI and lab work done, Physical therapy but nothing more. He does have an appointment on Thursday with his PCP but she is not doing much more to help the situation. He has stopped playing sports, is not very active, and doesn't even like to go to recess. This needs to be fixed and i need advice and opinions on how to do so. I have done a internet research, but i'm not finding any local pediatricts that specializes in this sort of case. We are from Oregon. If you could please let me know what other things i can do, or try,that would greatly be appreciated. Thanks you so much.
