Pain Under Sternum And Left Ribs

my self all so, I would go to the er swearing I had a heart attack and then a little poodle clued me in. These chest pains were only on my left side and all incompassing of the lung and heart. How ever after many tests, the lung doctors said it was cramps from all the steriods. I was like, nice guys for telling me. One a sat, it was sooo sever I took some perschribed flexeral and they relaxed and then on sunday, playing with my new puppy. She jumped (all 5lbs of her) on that chest wall and muscle and it gave me the worset chest pain. It was then that I learned that it was muscle around the heart and not the heart its self. That was great to hear. How ever it didn't make my chest pain better, it also radiated down my right arm, but ecgs were normal. When its bad hit the er, because you never know. See a gi and look into heartburn, reflux.. Good luck :!: !
