It lasted about a week, so hang in there. Chewable gas-x is your friend, but do you have anyone that can help you by pounding on your back? Think burping an infant- it helps so much. I also tried to make myself burp (results may vary and include vomiting, so don't do that all the time...), but it did eventually go away. If it's pain in your shoulder, a heating pad helped with that.
Good luck; I remember how much it sucks. But you will get through it very soon. ❤️
