Thanks for writing your query.
After reading your post, I would suggest that you should get yourself clinically examined and investigated by a Cardiologist.
Following investigations will be helpful in knowing whether your pain is cardiac in origin :-
3. Full lipid profile
4. Cardiac enzymes.
Your blood pressure is also raised and needs medical attention.
Medical management can be planned according to your clinical evaluation and reports of the investigations.
I hope this is helpful to you.
