For the last 3 days i feel like a weight right where my solar plexus is so i guess what i'm feeling is my stomach. During the day it's rather light but at the end of the day it gets worse, like there's a rock in my body. I'm also having trouble breathing and atleast 2 times a day i will take in a breath but feel nothing coming into my lungs. I'm 20 years old, could anybody help me?
