So am a 15 years old boy. So 2 weeks ago, I went to the doctor because I have been feeling uncomfortable in my stomach and it was hard to sleep. Sometimes there is little pain in some part around my stomach and I sometimes will burp a lot and tend to have nausea in the morning after waking up. So i went to the doctor and told him whats going on and he said that stomach acid is eating my stomach as am not eating breakfast. So he told me to change my lifestyle so I started eating breakfast, exercising, sleeping more and eating healthier. Since its been 2 weeks now, the uncomfortable feeling is not as bad but I still feels uncomfortable when going to sleep and I had to sleep with stomach facing down. I still have nausea and after a meal, my throat feels weird and I will feel like vomiting but it goes away after 10-15 minutes. Some day feels better than the other and all the doctor asked me to take was a liquid antacid and the burping has reduced too. I was wondering if it takes longer for my stomach to go back to normal or I might have stomach ulcer
