ok thanks for the details
however i need you to be a bit more descriptive about where the pain is... it is difficult for me to narrow down the list of possibilities if you don't localise it. chest pain can be caused by muscular, heart, lung or abdominal problems... so there are many possible causes.
to help me narrow down the list please could you tell me:
What do you mean by over your heart? as in describe where on your chest the pain is.
Same with brain and carotid artery... please could you describe the location in relation to the outside rather than inside of your body?
Is the pain worse if you take a deep breath in?
How about if you lie down?
Is it worse after a large meal?
Do you ever get dizzy or pass out?
Would you say you are generally fit and healthy?
Sorry to bombard you with questions - I'm just trying to get as full a picture as possible.
