Well, it stared 3 days ago. I got a really bad headache and I felt very light headed. The next day my girlfriend spent the day with me to make me feel better but I had very uncomfortable stomach pains. It wasn't sharp or throbbing just uncomfortable. I can't figure out what the part of the body is called, but if you run your finger along the center of your rib cage, once it stops and it's sorta squishy. That part, that feels tight and uncomfortable. Also at the top of my sternum where my collarbones have the little gap in between them at my front it feels tight there too. I've been having burps occasionally and trouble sleeping, someone please help me figure this out. It's my 3rd day and I've seemed to have gotten better but I still have a tiny bit of discomfort.
