I've been experiencing constant nausea (it ranges from mild-severe, but most of the time it is pretty mild) for the past few months, accompanied by a shooting pain on the left side of my chest. My throat feels like I'm going to throw up 50% of the time, and I seem to be dealing with a loss of appetite. I don't have a fever, but I do experience mild, dull pain in the front of my head. I experience a general queasiness everyday, and am always slightly lightheaded. I have tried fluids+rest.
