Question: 39 year old female. Normal weight, healthy diet.  Diagnosed with reflux in the Fall presenting with Severe globus. Symptoms diagnosed by ENT by laryngoscope. Around the same time early Fall  began noticing onset of current below symptoms. 40mg prontonix started December with some improvement of globus symptoms. 

Current symptoms which also started in the fall. These symptoms of concern Intermittent Upper middle epigastric discomfort / pressure. Not necessarily a pain. Mostly related to during and after meals  Can go two or three days without symptoms, and not every meal causes it. Worst after lunch or evening.  Usually subsides gradually. No nocturnal symptoms, wake in the morning without symptoms.  Symptoms don't start again until food starts being ingested.  bloodwork normal. No nausea, vomiting, weight loss or loss of appetite. In fact, get starving feelings, at the same time sometimes as the discomfort. Like fullness in upper stomach, hunger in lower.  No notable change in bowels. Lifelong IBS C sufferer

I tried to google my symptoms, and gastric cancer seems to present with these same epigastric symptoms. Needless to say, I'm concerned. 

Thank you, Doctor. 
I do have some follow up questions: 

1. The discomfort I mentioned does seem associated with meals. It doesn't feel like indigestion.  It is like a fullness or pressure, and I would say it can begin after only eating smaller amounts. I mention this because I don't know if that was clear in my initial post. Is this "early satiety" also consistent with acid peptic disease?it's not every meal, but it's frequent.  Also, the symptoms can sometimes last hours? 

2. Heartburn is infrequent (3-4x month at most). Could acid peptic disease cause the epigastric pressure/ fullness I describe without having heartburn?

3. The location of my symptoms is localized. Meaning, it's exactly in the center approximately 1-2 inches below my  sternum. Sometimes I can even press on it and it's tender. It's not painful in the sense that it makes me recoil, I can just palate tenderness on the spot that my symptoms seem to generate from.  Like pushing on a slightly sore muscle. Is this consistent with acid disease? 

Ive been on the Protonix now for a few months. Im wondering if i would benefit from increasing the dose to twice a day. I am making an appointment with a GI here in the states, but obviously my concerns are getting the best of me. 

Thank you for your timely responses. I just have one last inquiry, and then I will let you go. You've been very helpful. 

In peptic acid disease, what is the physical cause of the post prandial fullness and/or early satiety? And unlike true "indigestion", why would it hang around for hours?

I know I keep harping on the gastric cancer, I just lost two friends recently, so it's plaguing me. I know there's no way to diagnose without EGD, but are there any differences you've seen between tumor presented  epigastric symptoms and acid peptic disease symptoms? I'm assuming not, hence the scope. 

Finally, you mentioned the post prandial fullness being related to colitis? I've never heard this before, I'd always thought colitis was in the colon and felt lower. Are you referring to something different? And is this part of the acid peptic disease?

Thank you, again. You've been very helpful and I greatly appreciate it.
