I have had sudden spinning sensation inside my head( not outside, vertigo) several times. I have previously diagnosed with gerd and I think the spinning sensation is caused due to some food triggers. Can dizziness be caused by acidity? After the spinning sensation i feel Unsteadiness for upto two weeks and have reduced quality of life. I also have some dark spots floaters in eyes. What condition cause these symptoms.? Im facing these problems for the past three years.
