Im amanda i have a question.. ive been having chest problems in the sternum area it feels like pressure but i can breath fine but it gets miserable at night to sleep sometimes. And sometimes when i drink coffee or anything with caffine it does it. And i was super stressed out from work from mothers day week. And i think i might have anexity.ive had my chest wall reconstructed 8 years ago from cancer in my spine and i have metal rods. What should i do about the chest problem?
