I had the pH Bravo test done last week. I have to be honest and tell you that it was not the pleasantest of experiences for me though hopefully it will be just fine for you. The insertion itself was a breeze as you are knocked out, its just once you are awake again the feeling of the probe sewn into your esophagus is quite uncomfortable. I found it very hard to swallow and each swallow caused spasms of chest pains radiating out to my back so eating was not much fun. Its pretty much the same sensation as having a large gumball stuck in your throat. The funny thing is that they tell you to eat normally - well that's a joke, and the probe itself caused a lot of belching to relieve the pain and pressure which is recorded by the pager device. I don't normally belch anywhere near as much so I'm sure it must affect the results. I found I was OK as long as I wasn't swallowing so luckily sleeping was OK. The test is over in 48 hours but the bad news is that the probe can take much longer than that to detach. In my case it took 7 days which felt like forever, I was beginning to worry that it might never come out but I can't tell you how wonderful it felt when I swallowed and finally realized it wasn't there.
I'm sure its less inconvenient than the 24 hr monitor but at least with that one when the test is over its over. All in all its probably worth getting it done just so as you know, and its not that bad but I think its better to be prepared for an extended period of moderate discomfort.
