I am having on-going Vertigo like issues for a week now, my GP saw me last Friday and ordered blood work to check vitamin levels and for Diabetes ( I am in great physical condition and a healthy diet). I had these symptoms 4 years ago and it went away,; however, now it has come back more severe. If blood work comes back ok, should the next logical step be to see an ears, nose, and throat specialist? I am 50 years old with no current health conditions.
