After stiches in oesophages - still hiccup badly on certain occasions during eating three months later. is that ok?

Hiccups: Since you have been having strong hiccups frequently just since having esophageal surgery, it would be best for you to make an appointment with a gastroenterologist for further evaluation. Otherwise, please make a follow-up appointment with your surgeon to discuss post-surgical symptoms. Hiccups are usually benign, but since you have had them since surgery, a follow up would be best.
