Thank you for the responses. My medical is due in a couple of months. I think I will take some more time on my decision to self disclose. My symptoms are minor and would take a 10 minute conversation for someone to notice the slight uncontrolled deviations in my voice. I certainly hesitate to proceed with additional medical tests, even though I would like to seek proper treatment, but after a 4 year aviation degree and the cost of a private license through ATP plus additional "fun" ratings, I am not willing to risk my investment just yet.
If anyone has dealt with spasmodic dysphonia before, please advise on how you communicated this with your AME, the FAA, and what the final outcome was!
Thanks
