I am new here. My 16 year old daughter has suspected CRPS (from her Pedi, has appt with Neurologist next month). It all started with a knee injury after a fall during a hike 2 years ago. I'm wondering if anyone has used vitamins or supplements to help with the pain? I've read a great deal recently about Benfotiamine (fat soluble form of vitamn B1) being helpful with Neuropathic pain. Does anyone have experience with this or other more natural remedies?
