The most common symptom is the feeling that food (especially solid food) is stuck in the lower neck or under the breastbone (sternum).

A device called a dilator is passed through the narrowed area to stretch the ring. Sometimes, a balloon is placed in the area and inflated, to help widen (dilate) the ring.

Swallowing problems may return. You may need repeat treatment.
