The symptoms that you describe after eating the Chinese food sounds like trapped gas in your intestines. There are great yoga poses and stretches that you can do to release that trapped gas, that you can find online.

I have terrible digestion, due to my thyroid disease, so foods that normally never caused gas before now do, and if I don't do those yoga poses after I eat, I feel like I have a tire wrapped around my stomach and upper chest.

Also, walking before a meal for a minimum of 20-30 minutes, and not drinking liquid with your meal also helps with food digestion. Even if its walking in place, or up and down a nearby staircase, or up and down on a stool. Movement before a meal gets the digestive juices flowing. Of course, there's always Beano, or probiotics that you can take before you eat, that are supposed to get rid of the gas produced from undigested food. You have a lot of options. Good luck.
