When my voice dropped it felt like a scratchy throat first as well as during.
Every time I get so much as a slight cough these days I'm all "noooo it's deep enough... settle down already so I can work on being able to sing again!!"
But yeah...
I felt that scratchy sort of sore within the first few days of applying T in gel form and I sincerely thought I MUST be coming down with something cause there's "no way" it'll start dropping immediately, but that's actually what it was, so...
Maybe, maybe not...
"could" be.
