Sending you the best wishes, you are so young to have to endure RSD. I agree with others, get more tests and don't settle until you are sure. When I had my car accident, after the x-rays showed nothing, they did a bone scan, not pleasant but it shows things unseen on x-rays. MRI's can also detect other issues. I am not a doctor but perhaps mention these to yours. Wishing you the best of luck.
