What Causes Pain In Stomach Radiating Towards Neck And Nausea During Pregnancy?

I have a lot of stomach pain, that sometimes radiates to my back, and after I eat, even if it wasn t a fatty food. I am nauseous a lot after I eat. My doctor has also found a spot on my pancreas but doesn t seem to be too concerned about it. And finally I have an infected boil on my stomach that won t heal, even after two rounds of antibiotics. I also look like I m 7 months pregnant, I m not a small person but I m not a huge one either. Could all of this be related? My doctor thinks its acid reflux but I just don t think so.
