Sydney- many hugs!
I have the RSD in the throat/ mouth thing and it stinks! Still wondering what to do about it.
I have combined lyrica with: neurontin, valium, cymbalta, amitriptyline, darvocet and percocet. I have had nausea but not from meds combined (I don't think). I sure hope that all gets worked out for you!
What injections have you tried?
I know what you are going through, I really do! This is rough and it is hard to keep on going. Please know you are in my thoughts and prayers.
By the way, I love your name!

I just wanted to tell you.
P.S. I feel that lyrica really helps with my allodynia, as does neurontin (yes I am on both). Without this dose of lyrica when I eat I have allodynia in my mouth/ face enough to make me cry when eating. It has also decreased numbness. I have only found good benefits from lyrica and neurontin (other than dizziness when first starting it). I know others have complete opposite to say about these two, so I am just telling you what helped me.
