I have this constant pressure fullness in my upper left abdomen, somewhat under ribs but not entirely. Pressure is their constantly and is worst after eating. Some fooRAB make it entirely worst. After a heavy meal its a squeezing pressure almost and I can then feel it in my chest. With this pressure I get an itchy pressure in my throat. I been having this for years but now its getting unbearable.also when I press down on the spot where i get the pressure, it is sore to touch. After full meal i tend to feel more anxious than normal. what could be going on?
