Yes, the VA thus far has denied claims several times, each time essentially telling me that I would need to prove that agent orange exposure causes essential tremor. They have acknowledged exposure based on where my ship was. I do have a VSO assisting my claims, he is as upset with how the VA is handling my claim as much as I am. Thus, he suggested trying to connect my having had polio with the exposure but that would require an expert opinion. I already know how easy it is for me to get fatigued, and I deal with the tremors and ED issues to boot, to be totally honest.
