Just out of curiosity, what does USMC stand for? Are you treated by military doctors?
What type of voice and breathing problems do you have?
I had breathing issues when I was still really hypo. What thyroid replacement medication/dosage are you on? Maybe it's not enough. What are your current thyroid hormone levels? You should be getting tested for Free T3, Free T4 and TSH on a regular basis.
Please post whatever test results you have, along with reference ranges, which vary lab to lab, so must come from your own report.
