I'm sorry you're suffering so much Jerie. I had similar stomach and pelvic pains and found out I had endometriosis. Maybe ask your gynecologist to do a pelvic ultrasound and CT. I'm no dr but I understand stomach pain all too well. The rsd may be making it feel worse and you could have an UTI too. That could cause the burning when urinating. A simple urine sample and antibiotics can help cure that. I hope you feel better soon. Take care my friend.
