I just want to throw a quick note in here: the DoDMERB staff are excellent at their job and do their best to help people through the process. They have strong integrity and work hard to help you out when they can.
Unfortunately sometimes the answer is no. Sometimes they will grant a waiver, and other times not. This isn't just something they pull out of a hat, they go through the process of going through the paperwork, going through the medical records, and weighing it against the needs of a military force still at war.
Thousands of applicants and the same fair treatment is given to each individual.
Like I said, sometimes they just can't medically clear you for one reason or another, but it is based on the individual, and they know that they are working for people, not numbers. They know lives and careers could be at stake, and take their duty very seriously.
When I went through this whole process last year it was nerve wracking, but I knew I was in good hands. Larry for example does a tremendous job addressing the needs of people on the individual level. He will do the research, look up records, respond to emails, and call you to make sure that you are informed and to help you through the process.
Some people reading this will unfortunately be denied a medical waiver, but it's important not to get mad at DoDMERB, or to feel like it's the end. There are always options out there to serve this country, and you should always have Plan B ready.
