If the pain is in your abdomen, then you may need a CT scan. If it's in your chest, then this is your heart or lungs, thus you may need to see a Cardiologist or a Pulmonologist.

First I would like to ask if you have ever had a Panic attack? A feeling of anxiousness, shaking, fluttering in your chest like your heart is rapidly beating and slowing all at the same time? I ask this because you say "having woke" secondly I would be curious as to your diet prior to bedtime.
