What Causes Dizziness And Nausea With A Normal Report?

Thank u doctor. I have been to a cardiologist and had all tests done...tmt,blood echo etc.also checked thyroid,had chest xrays.

But for the past 5 years ive been having dizziness,nausea,tight feeling in my chest,head,ears blocked,palpitations,tremors,sudden pains that come in different parts of my body and disappear,dry mouth,neck and back and leg. pains.Im fedup of going for checkups.They cant find anything wrong.Is it severe anxiety as they tell me it is?
