Talk to Gastroenterologist on BURNING IN STOMACH

AOA doctors, This started 2 days ago, I had sehri (the regular sehri I've been having since 2 years) and since the evening of that day, first I started feeling like there was gas in my stomach and I tried to get it out through belching and it has gotten better not gone completely but now whenever I eat anything spicy, I feel this burning sensation in my chest very light burning sensation.

please note that this burning sensation only lasts 40 to 50 seconds and not after eating spicy food but while eating it. After that, it's fine.
