The tests are REALLY important
The pH test normally goes through the mouth if it's a Bravo capsule test. It goes down the nose if it's a catheter type. Bravo is a 48 hour test. Get your doc to explain more to you!!!!! You can ask for sedation for this one because it's always done after the manometry.
The manometry test goes down the nose and the nose is always numbed, but you don't get anything more because they want you to swallow a little water so they can measure how well your swallowing reflex works.
My experience was pretty awful, but also the worst possible case because I have a pretty rare bad gag reflex. I also have a tiny nasal channel because of it being broken 4 times. If you can get your pinky finger past the tight area your nose is normal. I can't. Technician and nurse couldn't get the manometry catheter down my nose. The doc couldn't either. He had to use a baby scope to get down, then put in a wire and then thread the catheter over it. The manometry tube is so small and flimsy it kept curling up in my trachea. He refused to do the pH that day because I didn't have a driver and said I needed sedation.
I went to another hospital for pH where a nurse tortured me and finally let me lie down. That way I didn't pull out the wire with the capsule. Remember that part of the trick! There's no reason not to lie down! They always want you to sit up, but there is more than one way to get the job done.
You really HAVE to have these tests! They are not fun if you gag horribly, but most people don't have a terrible time!!! Your surgeon can't get a proper idea of what needs to be corrected without the tests!! If I got through it, anyone can. But I should have been sedated for the second attempt at the pH test. You do need a driver for going home after sedation, so bring one just in case.
