hi, I was told I have a inflamed sternum. was smashed between dock and a boat two years ago. doctor said go back to work will take time to heal. did that now two years later been hurting for a long time. did a lot of lifting at work. I changed doctors he said I have a inflamed sternum. I have not been working for about six months. I own a restaurant went to work thought I could work at my desk. when I was home that night I had such a bad pain in my chest. after about three minutes went away. put a scare in me. I am a person that is used of going all the time. new doctor said no twisting turning lifting. I have not doing a whole lot. reading about exiity I do have that. it explains a lot. go back to doctor in a month. I have to get moving
