it feels like someone has taken my heart in their hands and just started squeezing it. l have no idea what it is

you must go to the doctor right now,drink more water ,eat healthy food and do not put yourself in the stress

Do you have any family history of heart problems? Well you might have contracted something. l recommend that you immediately go to a doctor right now.

never take your heart for granted. go to the nearest hospital and cardiologist will help you know all of this. it might be just acid though but whatever it is, do not gamble on your health. exercise and watching your food intake helps. stop smoking (if you do)and drink occasionally only.

GO TO THE ER IMMEDIATELY

Depends, has it happened before? Does the pain go anywhere else? When does it happen?

-I've had a related problem for about three years & l have not died yet. Though, my parents made the assumption of calling my heart troubles a bone problem, so make sure to explain it correctly to the doctor+family, which u should asap. If you've got squeezing pain, & do not get ur heart checked out thoroughly, u might miss something & end up like me in serious pain everyday =
l am just now getting the right testing done.But its so bad now l can not work or do much of anything, but do not let it get u down, & remember to see ur doctor - !
