Pain right below sternum

Ay

So I'm 25+6 And what started out as back pain(I thought I pulled a muscle) on my upper right side has now become excruciating pain below my sternum cutting straight through my body(it feels like there is a big pole stuck through my spine and out my sternum).

It is painful to breathe/move/stand up/sit/lie down/ cough /hiccup etc.

Is this normal?

Also my upper abdomen appears swollen now.

I feel like my food isn't leaving my stomach(I ate 4 hours ago and anytime I breathe out or cough, the food I ate comes back up. )

Anyone been through This?
