Vocal strain help
So im a 28 year old woman. I have had issues with my throat since may of this year. I am a physical therapist assistant and I speak alot to patient everyday. I noticed my threshold for speaking has diminished. It doesnt make sense why my voice is getting so tired so easily, when i use to be ablw to talk alot without any issues. Like my throat muscles feel so tired and strained after work. And my voice will crack on certain words or gets kind of raspy. It gets better but other times it will improve the less I speak. Im planning on going to a doctor about this but waiting on an appt. Anyone deal with this or have any idea of what this could be.
