This question needs more information to give the best answer. I am wondering if you might have gallbladder disease, gastritis, ulcer pancreatitis. This concern can include your need for an emergency visit now. You can try to triage this with a telemedicine visit, it is best you see a doctor in person

Take OTC antacid and avoid spicy food for a few days. If not better pl see your MD not the urgent care for exam. I think you will be fine.
