Brief Answer: Detailed below. Detailed Answer: Hello! Thank you for the query. If this strange pain/sensation is in the esophagus, you should be able to feel some change when swallowing water for example. Such symptoms can be caused by esophagus inflammation due to acid reflux disease. As you have hiatal hernia diagnosed, esophagus inflammation should be the first thing to be checked. Throat inflammation, salivary glands inflammation or even stones can also give such symptoms. In such case, the pain should get much more intense when swallowing. I suggest you to visit your doctor. Throat should be carefully examined at first. If no inflammation will be present, you should consult gastrologist and have gastroscopy done once again. Hope this will help. Feel free to ask further questions. Regards.
