Thank you for sharing this. Most hernias occur due to trapped gas. These gas bubbles can be quite painful and pressure the surrounding organs, such as the diaphragm (breating difficulties). In Ayurveda, is is called excessive Vata (= wind, gas). What counteracts Vata most is oilyness. Oils can removes gas quickly, either in the upward or downward direction. In your case it was through burping. It is good you followed your instinct.
