thanks for the query,,
pain in the chest can be due to many reasons..
1.musculoskeletal 2.lung causes 3.cardiac causes 4.neuralgias,,
..of these cardiac problems can be serious and need emergency intervention..
it can also be sudden muscle twitch or spasm..(for which you need pain killers,muscle relaxants)
usually cardiac pain is like gripping,on left side ,radiating to arm,face,back usually last for few minutes (angina
)associated with exertion,sweating,anxiety
,fear,shortness of breath
,diabetics,hypertensives,or any apparently healthy individual..
early the diagnosis ,better the treatment and outcome...ASPIRIN
CAN PREVENT ANGINAS TO SOME EXTENT BUT NOT TREAT HEART ATTACKS..
AS YOU HAD PAIN WITH HYPERTENSION
i suggest you have an appointment with a dr/cardiologist,get ecg,chest x ray,2d echo,tmt,angiogram gen,health check up to rule out any problem
and get well soon.....bye take care
