Dizziness, back pain, chest pain and anxiety - how are they related?

I ve been experiencing dizzyness on and off for over a month. It was really subtle at first so I wasn t sure - just felt nauseous and weak all the time. Went to the doctor and got prescribed benzodiazepines which help a lot. The dizzyness is very similar to a subtle boat - rocking sensation but doesn t seemed to be triggered by unusual movement as ornate is with mal de debarquement syndrome. It sort of just comes and goes through the weeks and I treat it with medication as need. However, in addition I ve also been getting noticeable but not debilitating back pain that throbs either in my lower back or between my shoulders usually at the same time as the dizzyness. Some very light on-and-off chest pain (or light throbbing) as well. And with all this has been a constant anxiety, though I m not sure if it s due to the unusually symptoms causing me to worry or if the anxiety is a symptom. Any clue as to what this could be would be appreciated
