yes, i have had 2 of them. they found that the muscles in my esophagus were not working correctly. there are 3 main muscles, and mine were out of sinc. sometimes they can help this problem by giving you several types of medications. the one that helped me was Paxil. Not only does it help with the depression (you have because of all your health issues) but apparently in the right dosage, it can help with the muscles in your esophagus.the test is not very painful, the only pain is when they insert the tube in you nose to pass to your stomach. other than that, it iratates you each time you swallow.
