i am 22 years old,i weigh 73kgs. i have been having chest pains going on for about 7 years now. the pain i get stays for about a few days and up to about 2 weeks. i have been to so many doctors and they all give the answer that i have an iron deficiency, then i went to another doctor and he told me its a infection on my chest. the pain i get in the beginning is sharp pains that feels like its on my chest and back muscles, the longer the pains stay the more it feels as if the pain is in my windpipe as i take a deep breath. i try not to move too often because when my heart beats too fast my chest feels like my rib cage is squeezing. when i wake up in the morning the pain seems to be the worst.
