Hello, for the past 2-3 years I've been struggling with severe stomach pain every 2-3 months. I am female, 21 years old. It usually comes from out of nowhere, is debilitating and terrible the first day, then slowly goes away over the course of 2-3 weeks. It's not cramping! It's more so of a terrible burning, aching, radiating stomach ache. No vomiting, diarrhea or nausea. It makes me weak and incredibly fatigued. And I will be burping up air for hours. Sometimes tums can help a tiny bit but never decrease the pain a significant amount. I've had an endoscopy, C-reactive protein and ultrasound test that all came back normal. There are no food/activity/stress triggers. I'm getting desperate, anyone that has any idea or experience similar I would love for you to share. Thank you so much!
