Chest pain for past years yaw help

Okay so back last year one evening I started having this really bad pain in my chest like I couldn't breathe and it was just horrible and I knew it wasn't anxiety it was painful so I went to our local emergency department and they said it was acid reflux so I was like okay great you know nothing major so the next morning I get up I'm still hurting her all day that day and the next day and the next few days so I went to the walk in clinic several times they didn't even want to help me so they said well it's probably the same thing that the hospital said so at this point I'm just really ready to give up so anyways I make an appointment with a cardiologist he does a stress test and X-ray and ultrasound and says it's acid reflux once again so I let it go for a few months and just dealt with the pain and then finally I got to hurting so bad that I almost didn't even care to live anymore so I went back to the doctor I got a referral to a cardiologist in a different city very awesome doctor so I go in I'm telling him what's wrong and he starts immediately running tests and the test that he ran or as follows :;

1) stress test with dye

2) x ray

3)blood work

4) c.t. scan with imaging (dye)

5)he sent me over 2 the local hospital in thag town for an iron infusion due 2 mine being extremely low

6)24 hour heart monitor I had 2 wear

7) ekgs

And i can't remember if it were any other tests ran.. So he said I have tachycardia.. no biggie ..

Says I need 2 lose weight.. agreed..

But he says my heart & lungs are healthy.. So again I let it go even tho I'm still in pain.

So went back 2 regular family doc.

She sends me to lung doc. He says it ain't my lungs... So now I'm waiting to go back 2 my heart doc.. the pain is in my chest, middle & then in left breast, shoulder on left side that radiates down my arm, and sometimes goes to the right side,my back & just different places.. it's random and miserable.. help guys please

P.S. i can't remember if he done an ultrasound the 2nd time..

I've done everything I know 2 do..

The cardiologist has me on propranol for angina & has said I'm NOT at risk of heart disease like heart attack I guess.. any one please help..
