Hello. Thank you for your assistance in advance. In short, 4 months ago I was sleeping with a microfiber polyester comforter and noticed a grogginess in my throat. Got rid of it after I realized my voice had been compromised because of this comforter. I feel like it could have been the material or dust (mites), which in turn, caused an allergic reaction that has never went away. I've been groggy or weakness of my throat ever since. What can I do to alleviate this suffering - I want my voice back.
