Has anyone ever experienced their head feeling off all the time , like lightheadedness/wooziness that comes and goes?

Amber

I’ve had blood work run on just about everything, and it’s all perfect. BP is good, heart rate is good, I got referred to an ENT for possible vertigo, and all my tests were good. Could this be a dietary thing? Any recommendations on how to help this? Started about 4 months ago .. ENT said cut out salt which I am trying my best to do. The wooziness comes and goes , sometimes I feel nauseous...any ideas?
