This type of pain can be from a Gastro Esophegeal Reflux Disease or even a heart related chest pain.
Considering your history of high blood pressure, diabetes and Cholesterol, I would advise you to first rule out a cardiac cause by having an EKG done.
That should be your immediate concern.
I would advise you to consider going to the ER to rule out a Cardiac Chest Pain, if this is ruled out, you can pursue other non emergency causes like GERD or chest infections, etc.
