Can you explain your rebuttal process and how to convince them you were misdiagnosed?
Long story short, I contacted the help desk, explained that I believe I was misdiagnosed and attached a letter from my doctor as well as some relevant medical information. They told me basically to hurry up and wait, but I kept emailing the help desk about once a week with new information or simply asking how it was going. Eventually, the help desk said I was disqualified due to the regulations set by DoD Instruction 6130.03. I googled DoD Instruction 6130.03, and found out in my case what I had was only disqualifying if I had certain symptoms for 3 months, when in fact I had none of the symptoms period. After contacting Mr. Larry Mullen, he notified me that my file will be reviewed again, and any new documents I had sent to the help desk would be uploaded immediately instead of the usual 1 month wait. It's still on a first come first served basis with being reviewed, so I am still waiting to hear back.
The best advice I can give is check DoD Instruction 6130.03, make sure that you were actually misdiagnosed, and then be persistent with contacting DoDMERB. Don't let up until they tell you they are going to review your file again. Hope this helps!
