Among two vocal cords, if one gets injured, any remedy to cure that?
As with other physical injuries, you must work with a doctor. The doctor will hopefully prescribe speech therapy, which you should definitely do. Hopefully, as you change the way you use your instrument, the dysfunctional cord will heal without surgery. You must also be very careful because once one cord is injured, it often causes problems for the other. I can’t emphasize enough how important it is to get professional medical help as well as follow-up with a certified speech therapist.
