Hi I read your query and understand your concern Pain in chest can have a lot of causes, most of them are not risky so you don t have to worry too much It may be muscular or any anxiety disorder The only risky cause is cardiovascular which seems you have excluded lately Depending on its characteristics doctor can judge about the cause If you have pain during physical stress you need to be checked by a doctor If pain bothers you during rest it is probably muscular or from anxiety Any case avoid caffeine and energy drinks and use healthy diet, full stop of vegetables Wishing you good health don t hesitate to contact for further questions Best regards
