I've had it for about a year and it really gets in the way of things. I'm a 15 year old male and it isn't muscle, it isn't respiratory but I have been seeing a physiotherapist and he believes it is bone related, for example the structure in my upper spine or ribs or whatever. He says it could be related to the thoracic area. He gave me exercises to do but they only seemed to keep the pain settled for a while, because sometimes my chest aches. The pain is only in one area and that is the right of my chest (my right). It really riddles me.
No it definitely isn't heartburn
