Dear Grey,
I am sorry you are have so much trouble getting care right now. You can always request a copy of your record from the visit in question and see if it is accurate. It may be quite different than the letter. If it it's NOT accurate then within thirty days of the visit they can easily amend the record. You would need to send them a correction, Mark through inaccuracies etc. I have done this myself in the past when a visit record had mistakes. Then get that info in your current doctors record. This will trump the letter.
Exercise your power of choice and walk away from doctors whose care is not in agreement with what you feel is best for you. There will always be differences in approach and difference of opinion. I have had several doctors I have consulted that I just chose to never see again.
Also keep in mind that Recommendations change over time and many go to SCS much sooner and on more cases than ever before. For this reason I have avoided docs who specialize in mostly neuro modulation, feeling that their personal bias might be to steer me towards treatments I don't want. Keep up the search and don't settle. There is good care out there.
I hope you find relief soon! Sending Hugs,
