Well I have RSD/CRPS along with other medical issues like EDS and some things they can't figure out yet and I'm currently in Dallas Childrens Hospital and they are having me do intense OT and PT which is a treatment for RSD that once did help me some so were trying it again but more intense and I'm having a really sharp pain behind my knee and I told my physical therapist and she said it's normal and I'm wondering is it normal? Or should I tell my nurse or doctor about it?
