For the past week I've been getting on off stomach aches that have gotten worst as the week has progressed. It started Saturday and the other day I realized I only get it after eating or drinking. At the end of August I got heart burn around 3 times but I haven't had it since. I'm having stomach pain around my belly button area and I'm worried about visiting a doctor. I also feel more full than I used to but I still have an appetitie and I haven't lost any weight. Should I book an appointment and get checked out? It could be something like acid reflux or GERD but those are also symptoms of stomach cancer so I'm a bit worried.
