Grey,

Sending a malicious, inaccurate letter is certainly inappropriate on multiple levels. I would encourage you to get the record, address any inaccuracies in writing (that request will go in your record) and THEN start process with your medical board if you decide to file a complaint. That is what they are there for and they do take investigations seriously. If record keeping is inaccurate, that alone is enough to get their attention even without the letter issue. My point is you have recourse for the issues at hand and I know you don't want to carry this stuff in your record (letter included) going forward.
