I feel airy/spaced out, my chest feels like air bubbles that make me burp. Slight nausea then goes away. Pressure in chest up my neck in my face help?

# possibilities. The airy and spaced out feeling is concerning. The possibilities would includema drug effect, or something that is causing changes in your brain. Pressure in your chest and some nausea could be symptoms of a heart problem. The air bubble sensation may mean some acid is being refluxed from your stomachs to your esophagus. See your primary care physician.
