I have pain on my right side of my chest and it escalated to my arm then my hand. what could it be. should i go see a doctor?

Get evaluated.: Any chest pain with involvement of the arm/hand should be evaluated - as this can be a symptom of heart attack. Other symptoms include pressure or tightness under the breastbone, pain or pressure in the jaw or neck, shortness of breath, indigestion, light-headedness/dizziness, and of course, left-sided chest pain. Better to be checked out for a false alarm than miss an important warning. Lgromkomd.
