I had an laparoscopic nissen fundoplication procedure last week, and already i'm suffering from recurrence symptoms, my sore throat, what should i do?

Call your surgeon: The easiest and smartest answer is to talk to your surgeon first they will know your body and the nature of surgery better than any other person on the internet. Having a sore throat after a nissen is very typical especially if the surgeon had to do endoscopy during the surgery or a bougie to help size the nissen wrap. Some sucking candy may relieve the soar throat.
