Hi. i have two questions. i'm a singer/voice actor and i am losing my voice. i'd like to know ways on getting it back quickly so i can practice again?

Rest: You might need some rest, specifically voice rest. Also an ENT exam would not harm at this stage trying to understand early if there any specific anatomic abnormality that might limit your ability to continue singing/acting at a professional level. Not to mention the possibility of an acute condition that should be self limited. Thank you and good luck in your career!
