chest pains . maybe tietze syndrom?

hi! First of all im very glad to hear about this oportunity to write directly to a doctor for free. Beacause i don't have so much time right now ill go directly to the issue.
Im 24 years old male from Romania (south east europe); and i have been having very bad chest pains for about 2 years now, maybe since it started.
It all started with a horrible pain in the left side at the heart area and moved to all the left side , a little also in the back. First time was very bad and and i coudnt eaven move , thouht i would die, was hard to breath and coudnt move only very slow, this lasted a cople of days, after that my pain completely dissapeared ,after about 6 months i got again the same pain ,started in heart area and bethween my ribs, this time i was so scared because was more bad and lasted more; after an EKG my doctor said i have NOTHING! eaven if i felt ill die , pain was very bad, and some other nurse from my doctors room decided to give me calcium shots assuming this was the problem , without any other test.All the time my doctor said i have nothing wich is crazy, maybe is the system here wich is very bad. Anyways after the second strike all the pain moved since about one year ago under my "chest bone" , everyday pain is there , many times is horrible , i feel like somethiong very heavy is under my chest, im so sick and tired of it, i hope somebody can help here nobody can. I did also an x-ray to my lungs and with lungs all is fine. i just assume it is tietze syndrom, i studied all it can be and this for me seems to be the problem but im not sure beacause all symptoms are not 100% the same.Now i only use a cream called Embla. Thank you very much i apreciate any help .God bless!
