I'm sorry that your Doctor is being so awful to you, that isn't right

. I agree with what Joan said, please go and get another doctor that will listen to you and not judge you if you can. It is SO important with this illness that you have a doctor that understands what RSD is and knows how to treat it!
I'm glad that the nurse WC hired is believing you now, that is great and I really hope she is able to help you and try and get things fixed. I'm also glad that you are getting the MRI scan done and hope that it will give you some much-needed answers.
Please keep us updated and if you can, try and get another doctor.
