I have been experiencing nausea on and off for the last 2 weeks. it is accompanied by a sore throat but only on the left side of my throat. I checked my temperature about 10 minutes ago and it was 99.9F. twice in the last 2 weeks, I have experienced extreme discomfort in my upper stomach where I felt like it could explode through my skin. it was not necessarily painful just very uncomfortable where i felt like i could not move and when i did stand up I felt a little light headed. i have no known allergies. i also had a headache at the start of this but i feel like it is unrelated.
