I’ve had this problem for many months after I got covid but have been so depressed not in the right state of mind to go to the doctors. A major change in voice as In my voice has gone so husky ( I’m a girl) . A lot of mucus and feel like there’s a lump in my throat when swallowing. I’m 18 so I’m so lost on what it actually is please can anyone help on what it may be. Thanks 
Its possible that your voice is changing as you go into womanhood. This is something natural, but i believe you should speak to your GP.
