Thank you chershell for your question.
It can be quite frightening to have these uncomfortable sensations. Have there been big events in your life recently? Have there been huge changes in your weight or diet recently?
Nausea after food and pain over the lower rib cages can be quite common symptoms. The cause can range from something normal to something dangerous. It can be hard to tell. You should visit a doctor soon.
These are seldom terminal though in my limited experience. The common causes are:
1) Gallbladder problems. Quite common, perhaps try to completely eliminate oily food from your diet. If persistent, needs a scan.
2) Gastric problems. Try regular meals, small frequent meals instead. If persistent, might need further testing.
3) Heart problems. Less common. Need to see doctor to diagnose.
4) Other weird causes: tight bra, severe obesity…
Take care and hope you can find relief soon.
