[Mom needs help]

Hello,
My 8 year old daughter was just diagnosed with CRPS two days ago. I am beyond worried. She has been in constant pain for the past 2 months. Our pediatrician said that he could find nothing wrong with her and said that she was engaging in drama. Her injury is on her shin and I had to get crutches so that I could stop carrying her. He told me to take away the crutches and tell her to get on with it. I was lucky when a neighbor happened to see her and recognized her symptoms. She knew that name of a specialist and my daughter was finally believed. She cries in pain every night until she passes out around 2, 3, or 4 am. Therapy starts next week, but I can't imagine having her go through this another day. We live in Connecticut and her specialist is affiliated with CT Children's Medical Center. When my child is in pain how can I sleep?

She was taking melatonin...This helped her with sleeping tremendously, but her doctor took her off this and added Amitriptyline for pain. It does not help her sleep and she is in pain. She has been on this for two days. I'm so worried!
