Hello, I'm An American Living In China. The Healthcare In

Hello, I'm an American living in China. The healthcare in my area isn't the greatest, and it's difficult for me to communicate with them, so I appreciate your advice.
For about a week I've been having indigestion problems. It's common here to get food poisoning, but this seems to be something more than that. The symptoms come and go, but there is a steady discomfort. Sometimes I feel bloated, sometimes it feels more like heartburn, other times it just feels really tight like my stomach is making a fist. Most of the symptoms are in the stomach region, but sometimes the discomfort spreads in the direction of my gallbladder, and sometimes I have discomfort in my lower abdomen.
