So you need to take my advice with a grain of salt. There are no guarantees with my advice because I'm not the decision maker for medical waivers.
My #1 advice is to get opinions from military doctors to the extent your resources and efforts allow. Civilians doctors who say a patient is able to perform all military duties do not have much sway with decision makers. Remember, it's not simply being able to perform military duties- it's also being able to do so in deployed and austere environments. Those who have never been there, done that OR never been trained to make that judgment simply cannot make an informed recommendation on who can and cannot be in the military.
For asymptomatic tachycardia, you should present the results a 24-hour Holter monitor. Is this tachycardia all the time or comes and goes? Need to include labs done to ensure you don't have anemia, hyperthyroidism, or pheochromocytoma. Just to cover all bases, I would have a psychiatrist say you don't have some type of anxiety disorder which can be a cause of resting tachycardia. Even though you're asymptomatic now, it doesn't mean you won't have difficulty breathing, palpitations, or dizziness when you're doing something as simple as the duffle bag drag in Kuwait going to the terminal to catch your C-130 flight into Iraq. A cardiologist should provide a bona fide diagnosis as you why you have tachycardia as the "norm." The explanation should include why no treatment is recommended. It might even be beneficial to have a cardiologist who is fellowship trained as a electrophysiologist do an evaluation on you. If your final diagnosis is Inappropriate Sinus Tachycardia, then that is a diagnosis of exclusion meaning all the other causes of tachycardia must be ruled out first.
When I hear (no pun intended) developmental disorders and hearing loss, then I wonder if they're connected. Many kids who have hearing issues also have difficulty with language skills or understanding what is taught in class which brings about the developmental disorder or delay.
The results of the pure tone audiograms (I'm assuming that's what you got) suggests to me you passed the standards. Are you sure the DQ is also for hearing? Are you above 35dB at any frequency?
What exactly is your developmental disorder? I'm not a psychiatrist but I'm thinking ADHD or autism spectrum disorder. It could also mean dyslexia, Tourette's syndrome (I had an attending one time with Tourette's and when he was mad, he'd suddenly start yelling, "Kill the medical student! Kill the medical student!" We'd just laugh it off because we knew it was just the Tourette's.), or other conditions. Again, what's your bona fide developmental disorder diagnosis?
The hearing was averaged at 23db at all freq except 4000hz which was 38db
I already sent them the holter study and they waived the tachycardia
The disorder is autism spectrum disorder
how would I find a military doctor to get an opinion from?
If would have been freaking nice if you would have said you got a waiver for tachycardia already.
Your initial post said your waivers were denied and you proceeded to list your DQ conditions. I assumed your waiver got denied for all of them. Didn't it strike you as something important to mention that you already got a waiver for tachycardia?
OK. I'll assume your hearing didn't get waived. There is a test called the Speech Recognition in Noise Test (SPRINT) test that only the military uses. if you can get yourself into a military hospital and undergo that test, then you may have a chance at a rebuttal if you do very well. If you cannot get into a military hospital, then a civilian audiologist should do some type of testing that distinguishes your ability to hear in quiet and noise (also, ability to recognize sentences with background noise). Any test where you will hear words and you have to repeat them will work.
Again, there's something else going on here because the numbers you provide appear to be within the hearing standards. Nevertheless, I will go with you telling me you were DQ'ed for hearing. Consider getting a recent eval from a psychologist too so the reviewers will have the latest on where you're at with the ASD.
Autism spectrum disorder... never seen it waived before, but you're throwing a Hail Mary pass here. I would get documentation of all you academic achievements
without any accommodations, use of meds, or support. It would help if you can document you've had a history of paid jobs. Your supervisors can then write a letter saying you did well will assigned tasks and showed up when you were scheduled to work. Any chance you're an Eagle Scout or been in CAP or JROTC? That would help some.
The DoD allows ROTC cadets to get evaluations in military hospitals for the purpose of determining fitness for military service. Are you in ROTC now? If so, then your unit should be able to link you up with a military hospital nearby. Costs (e.g. travel, lodging, etc) are on you though.
Good luck.
