Hi, I ve had nausea and been foggy/light headed with light headaches for about a month. All blood work has come back normal. Yesterday got prescription for amoxicilian as one ear was a little red, I am also taking prilosec for the nausea. Yesterday I felt great, no nausea, very light head stuff. Today head stuff is back, foggy/light dizziness/light headache. What would going to an ENT do for me? What could be going on?
