Hello my name is Shannon, I am 23, working as a full time manager of a fast casual restruarant. I smoke cigerretts every day; almost have half a pack a day. I have a fever, running nose sometimes if im near heat to much. I also have the chills, and my stomach hurts so much. I cant expand it and it hurts on the lower left side. Also my lower back hurts and this all happened pratically around the same time. The fever came a few days later. My head and body hurts so much. Please help!
