Have you had your thyroid ultrasound scanned, because you can have nodules on the
thyroid, which is in the throat,
and these can cause hoarseness,
and like a raspy feeling in the throat and voice.
I would have a thyroid blood test, and ultrasound of the thyroid, as this is were your problem might lie.
