sometimes it can be the fact that pollen & molds
were in the air during spring,
that causes laryngitus,
"swollen vocal chords" after that then comes the hoarsness which is what I have now.
I sing & my high pitches are gone.
The voice comes back, & it could take several months to get to full strength.
Drink plenty of water, decaf tea, & also wait for
the warm weather to break because I've lost my voice over & over again & it came back over & over again but!
It was mostly during spring/summer or warm environments.
what you want to do is protect it when it comes back.
stay away from mowed lawns during the spring. & stay out of the pollenated air as much as possible.
lots of water always all year. hot tea decaf.
& voice rest meaning no talking or singing.
God bless much love to you friend.
