pain in the chest left arm pins and needles

hi have this pain for years it comes and go ant i think i have a problem with my heart?i had so many tests over the years i cant remember always normal.i had been to er more times than the doctors who work there!!!i went to cardiologists pathologists all kinds of doctors everyone says the same tink its in your mind you feel the pains but you make them.does anyone have those pains?also if dont have them i pain somewhere else.today i start my cipralex 20mg dosage i have to wait up to 6-8 weeks to see if they are working.wish me luck.the only think thats make them go away is to ignore them but is very hard also if touch hard somewhere on my body they go weird right?forgive me if i become tiresome but i feel good if i right what i feel and with your answers.and i know i ask again but i need to hear it again if i had a real problem with my heart the doctors would have know it and tell me right?

thank you kraj i feel pain right now i might check that book too.

sometimes if i move it hurts on the left side of my chest so it must be muscle related right.god is so annoying and fearful feeling i really hope my meds will work i will try to ignore the pains as much as i can,if i stop thinking of them then my mind will too i think so,and thank you kraj again for your response
