Hi, im a 36 year old female and i am having pain between my breasts on both side and it is tender when i touch it. I work at at grocery store and i am lifting heavy things all the time. I went to my doctor and he said that i have the pectoral muscle torn, but it is so painful and i have it now for a while and i am putting rubbing cream on it. I am just afraid that it could be or turn into a heart problem. I dont have high blood preasure and i had an x-ray done a while back and an ekg done, normal heart sounds, but i am still afraid when the pain comes. Can anyone help, and tell me why its not getting better.
