Yes, its a MUST test esp manometry according to my surgeon. If the esophagus is not strong enough, he won't do the surgery for me.

As for the pH test, did it trice. Once is off medication & the other is while ON medication to confirm the acid level. Even with medication, my acid level is still very high during the 48hrs of the test.

Third time, is I went and see a professor who was giving me all negative comments & I did one with double dose medication.
