I am a 42 year old woman that is physically active and not overweight. I do not smoke nor drink. I have been experiencing burning sensations in my stomach for the last 2 weeks. I have tried prilosac and that helped, a little, but within the last 2 days, the burning sensation is now consistent. Sometimes I feel nauseous, but no vomiting and no lost of appetite. I am not belching alot. This burning sensation occurs when my stomach is empty and when its full. I have never had this problem before and I contacted my PC and I could not get an appointment until Monday, but until then, I am becoming concerned about this issue. Please help me to calm my nerves by giving me some ideas as to what could possible be going on.
