I have had an increase in smoking the last few months due to increase stress, i have been having cramping sensation in my chest with hot and cold flashes and surges of adrenalin, when i move my torso i feel a cracking/poping sensation usualy followed adrenlin to that area, ive gone to my gp eho gave me a chest xray that came back clear but the surges of adrenilin rushing to my chest are making it hard to do daily activities i feel wpund up like tight guitar strings and i notice the more i smoke the day befor the worse the symptoms are the next day. Im trying to quite but the anxiety it making it so hard.
