I have had every test done on my heart except a stress test and a heart cath i'm still having chest pain.. i am a 27 yr old female i smoke, overwight?

Smoking: Stopping smoking is 1 of the hardest things a person can do. Keep trying & failing over and over again. U'll do it. Smoking causes chest pain by itself, even without heart damage. Sooner or later it brings emphysema and cancer. There's not much doubt anymore. That doesn't make it any easier to stop. If you need help, hock your hubcaps to buy patches for 2 mos minimum. Gd luck!

Chest Wall Syndrome: Your case the the exact reason why our healthcare is the most expensive. Your doctors overlooked the simplest, most common but most confusion. Plain ole tender ribs and rib margins.
