hi jenna. i was told i had fibromyalgia a few years after i was diagnosed with rsd. my pm drs np told me that they have seen quite a few rsd cases who end up with fibromyalgia too. its not easy living with both but pain and antianxiety meds have helped me manage my pain a little better. and even though you can use some of the same meds to manage these i have read that they are different. though they both cause constant widespread pain only rsd causes physical symptoms as well such as swelling, temperature changes and excessive sweating. i hope you have a dr who can help you to mange both your rsd and fibromyalgia. soft hugs.
