In Korea, internal medicine is in charge of all stomachache-related tasks. Usually, we don't say "Please make an appointment with a gastroenterologist," so just go to the internal medicine clinic and tell the receptionist about the symptoms.
@Riaair I have been waiting until morning so, now that it's finally morning, I will be soon going to the big hospital near my house and was planning to get an appointment for a gastroenterologist so, I can get cured ^^'
@Riaair excessive burps and gas in stomach, chest pain, suffocation feeling in chest and throat because of burps & gas, acidity, especially burning in throat. many/lots of burps, burden on chest, pain & cramps in tummy, chest pain when I bend over or kneel down. therefore, a lot of difficulty in standing or even sitting because of breathing shortage from gas in stomach and chest and therefore, difficulty to sleep too due to feeling suffocation. feeling a weird pressure on nose as well.
트림이 심하게 나오고 위장에 가스가 찼어요. 가슴 통증도 있고, 트림과 가스 때문에 가슴과 목이 답답하고, 산 때문인지 특히 목구멍이 화끈거려요(or 따가워요 stinging). 배가 아프고, 허리를 굽히거나 무릎을 꿇을 때 가슴이 아파요. 가스 때문에 숨이 잘 안 쉬어져서 서있거나 앉는 게 힘들고, 그래서 그 질식감 때문에 잠을 잘 수가 없어요. 코에 이상한 압력이 느껴지기도 해요.
