Hi there,
Welcome to Neurotalk. I am so sorry that you are dealing with RSD.
Please let me introduce myself:
My name is Alison, I am 12 years old and I suffer from RSD in my left leg. I developed RSD in March after an ankle sprain. I was diagnosed with RSD/CRPS type 1 in July.
1 month after I was diagnosed with RSD I was prescribed Amitriptyline by my PM doctor to try and help me sleep. I developed a nasty side effect of 'blurred vision', this resulted in a knock to my right arm, and I was diagnosed with RSD 2 weeks later. My arm is now fully recovered thankfully!

I am sure you know that there is no cure for RSD. Treatment usually consists of Physiotherapy, Medication and Occupational therapy. Most people see a Psychologist too.
This is a list of medications I have tried:
Amitriptyline
Lyrica
Paracetamol
Ibuprofen
Morphine
Tramadol
Gabapentin
So far, I have not found a drug that works

It sounds like your pain could be independently maintained, this means that it takes longer for the medications to work.

Hope I have helped. If you want anymore information just PM me
Thanks
Alison
