Hi friend,
Welcome to Health Care Magic
It has no relation to the
pleurisy and
costochondritis of the past.
The pain is probably muscular – pain from the heart is oppressing, in central chest (and left), worse on effort, relieved by rest, may radiate to shoulders and arms, associated with sweating and so on.
Light headedness could be from anaemia (
iron deficiency) / you may have to see a haematologist and get investigated, if the iron deficiency runs in the family... /
Postural hypotension is a possibility / The body's balancing mechanism is in the
inner ear. An ENT (Ear Nose Throat) specialist may have to be seen, especially if there is ringing in the ears..
Disorder of rate or rhythm (
arrhythmia) may be responsible for the flutter and/or light headedness – especially with
mitral valve prolapse...
You have not stated your personal habits, co-morbidities, even age ...which could influence the diagnosis and outcome...
The ideal option is to see the cardiologist.
Take care
Wishing speedy recovery
God bless
Good luck
