I hope things improve with the change of medicine! I know that baclofen has really helped me... I could barely walk because of major tremors (I used a walker in the house, wheelchair any other time), then I started this and I am almost walking unassisted!! I can also use my hands better and they are pretty steady- a lot less tremors! So, good luck!
The amitriptyline might help her sleep... I hope so!!!
I hope things improve, she is in my thoughts and prayers. She can email me whenever... she has my email address, and I know what it's like to be young with RSD... I am there right now.
Huge pain free hugs for Alison, and hang in there Mom!
