welcome to health care magic forum,
your blood pressure
is not in control as it should be,you have not mentioned whether are you taking any medicine for that or not.if you are taking, dose should be revised,now trend is that BP
should remain 120\ 80.with medicine.
as you sometime get pain in chest
, it may be due to coronary insufficiency.
best advise is that you consult physician and seek his advise for investigations,like ecg
etc and treatment.
