URGENT PLEASE HELP!!!!!

Okay so for the 6 days I’ve had extremely weird things happen. So I’ll start off with my back.. I work at McDonald’s and its when I’m there I get absolutely horrible back pain. I’m only 18 years old and I’ve worked before.. it’s not because I’m up bc I’m actually pretty active . ( I always move around ) but the pain hurts to the point I want to cry. ( right now it’s hurting ) and this is where it hurts...

Now the one thing that scares me which is what the title says about urgent is a feeling of something WANTING TO COME OUT OF MY STOMACH!!!! for the last week and a half it’s as if something is pushing against my belly but inside me . I have no idea what it could be and I’m very frightened. Sometimes when I look down at my stomach I can see it pulsing. Please someone have maybe a clue of what it could be .. below I’ll show where I feel the pushing sensation ..

Thank you guys so much for reading if you did . I love eve so much . You guys are like a family to me .
