My daughter is 13, she has had bellyaches ever since she could talk, I've taken her to the doctor a couple of times, they say it is acid reflux . Does Acid reflux cause belly pain, I guess I always thought that was more in the esophogus area. Another sympton she has, is alot of burping. She could out burp any male around. Any adivise, I hate to have her on meds. Any natural supplements??
