The esophageal wall was thickened and narrowed, so I received a Botox injection.

My family members had thickened and narrowed esophageal walls, so water and food couldn't pass down easily.
Because the esophagus became too narrow, food couldn't pass through easily, so you always felt bloated and had stomach pain, which is why you were always taking stomach medication.

Since there was no improvement with medication, you received Botox treatment last week.
Botox treatments are said to take some time before the effects become noticeable, and the effects last for about six months.
And I heard that it's not certain whether Botox will be effective.
If Botox is not effective, they say you should try other treatments.

Has anyone experienced difficulty swallowing due to narrowing of the esophageal wall?
I'm also curious if there are any people who have received treatment for these symptoms and experienced positive results.
