I have acid reflux and right now I'm experiancing stomach pain?

My stomach feels very tight and in pain. I took DGL (a natural supplement) that's supposed to coat the esophgus and stomach lining to help discomfort. I also sipped Rajas cup (a tea) that helped a little but my stomach still hurts. I also had diarhea earlier. This sucks. What can I do? I really don't wanna take meds
