Hi, i'm getting sharp chest pain at random for 3 to 5 seconds only? i'm working in it company. blood pressure is normal. what would be the cause?

Not enuf info: Although it's impossible to say, my guess would be a muscular source because of it's marked brevity. Cardiac pain is neither sharp nor that brief. GI tends to be burning or gnawing with loss of appetite and/or nausea. Arthritis usually is on-going. Do certain movements or positions make it worse? Can you find trigger points by compressing the area that hurts? That would reinforce the dx.
