... breast from left to middle and then middle to left side. Then it has gradually gone into a burning like my skin is on fire. None of the doctors seem to know what it is and just ignore it. But I did have lung cancer in the past and had the upper left half of the lung removed. Daily I am having these waves of burning while I am in a resting state. And I sometimes wake up and feel that area under my left breast burning as if something is going to burn thru from the inside out. How can I stop this pain and find out what is causing it?
