shortness of breath along with a feeling of pressure around chest--
(1) AN UNDERLYING HEART DISEASE such as
acute myocardial infarction ,
valvular heart disease , left ventricular failure etc
(2) AN UNDERLYING DISORDER OF THE
RESPIRATORY TRACT INCLUDING LUNGS such as obstruction of the airways , bronchial asthma , pulmonary edema ,
pleural effusion , pleurisy , pneumothorax etc
(3) METABOLIC DISORDERS such as uremia , diabetes , hypokalemia etc
(4) MUSCULOSKELETAL like costochondritis , ribs fracture etc
(5) PSYCHOGENIC such as in acute severe anxiety
if i were your treating doctor,i would have advised you the following tests and investigations to evaluate and to make a precise diagnosis
(1) COMPLETE HEMOGRAM
(2) RFT's
(3) BLOOD SUGAR FASTING AND PP
(4) ABG i.e ACID BLOOD GAS ANALYSIS
(5) PFT i.e PULMONARY FUNCTION TESTS
(6) XRAY OF CHEST

(8) ECHOCARDIOGRAPHY
as soon as you get these tests done,you can send us a scanned copy of all your reports for detailed evaluation or you can consult your family doctor so that appropriate treatment can be started if required along with any necessary instructions and precautions
hope you find my advice to be helpful
take care
