Treatment for vocal cord swellings depends on the cause.
If it's due to overuse or inflammation from yelling or excessive speaking, voice rest is the first step. Reducing the amount of talking and whispering for a period of time allows the vocal cords to recover. Gargling with warm salt water can also soothe the area and reduce inflammation.
If it's caused by acid reflux, medications to control stomach acid, such as proton - pump inhibitors like omeprazole, can be used. These drugs reduce the amount of acid that may irritate the vocal cords.
In some cases, if the swelling is due to a growth or polyp, surgical removal might be necessary. This is usually a last resort and requires careful consideration of the risks and benefits. After treatment, speech therapy may be recommended to help with proper voice use and prevent recurrence.
