Suggest Treatment For The Burning Sensation In The Chest,arm And Hands

HI, I have been having a burning, ache in my left arm pit, chest, arm and hand. This past week, I had to leave work early due to feelings of tightness in my chest, nervousness, light headed, burning in my arm and some numbness in arm and hand. I had an ekg and xray all which came back normal, I seemed to only have these symptoms at work and occasionally else where. I feel very tense at work and do not have the easiest people to work beside. if this is anxiety, is it something I can learn to work with or should I start looking for another job?
