Both of my armpits are bruised completely, I have a lump the size of a walnut under each, coughing, wheezing, constant fatigue, nausea, vomiting, pain in my back under my ribcage, tender to the touch on my abdomin, and fevers, along with shakes and intense headaches. I am a smoker for seven years, and do not drink or do drugs. What could be wrong with me?
