I don't know if this is relevant or not, BUT I have had dried out hoarse throat for a few weeks now. I believe it is from DEET in the bug sprays I use on myself because I am outdoors a lot. I made the connection several years ago... I Wondered why my throat was always gunked up and painful when it was hot and humid out....noticed it was worse on bug-days (me being in the woods, out in unmowed grass,etc)
I try and use non-DEET alternatives but we have horrible chiggers here in Tennessee from May to August. One good infestation will make the trade for a sore throat seem like a good deal. DEET is so toxic it can melt polyurethane and lacquer.
MY GF has been having the same symptoms and we use the same stuff but she is certain she has corona....she also loved the media. Just thought I'd toss that out there
