Hello and Welcome to NeuroTalk, FabAfter27!!! I'm so glad you have found us as you will meet many great people here who will try and help you feel less alone if they can!!!
I'm sorry to hear that you suffer from RSD too!!

I really hope that you can find something to help you real soon and please know that you are in my thoughts ad prayers!!
I have RSD in my left leg and both arms so understand some of what you are going through and know how scary it is to be diagnosed with such an awful condition! I developed RSD when I was 12 years old after an ankle sprain and am now 14.
I hope you can find a good PM Doctor real soon as they can be really useful in helping to treat RSD as they prescribe pain medications, do nerve blocks etc! Have you seen a Neurologist? They can be really useful also and give you some suggestions.
As far as diet and RSD, there is a diet by a famous RSD Dr called 'Four F's Diet' that I found a while back and have been trying to follow. I can't say that it has helped with my pain that much but it is worth a shot as there are some foods that can trigger pain such as chocolate and caffeine etc. I usually find that if I have some chocolate, my pain goes up for a bit afterwards so try and cut it out as much as possible - even though it can be hard!!!!
The link to the diet if you want to check it out is:

Are you in Physical Therapy at the moment? It's extremely important that you keep moving as much as possible even though it is extremely painful!!! PT can really help some people as long as you have a PT that specialises in RSD and other disorders that are similar. You could do some exercises at home also that could help.
Take care and if you need anything, please know that I am here for you and will try and help you if I can!
