Light chest pains need advice?

okay so i have been having some light chest pain but its always felt like its been above the rib cage none of the signs of a heart attack. the pain has mostly been a little bit lower then my right breast and some over my sternum. also i have had some slight leg pain too. I believe that all of this has just been caused by bad circulation caused by me being so tall and also having to remain seated for long periods of time due to school but i want some reaffirmation before i just push this out of my mind.
