Hello, I am going to sound like a winer right now but just want to tell you my symptoms the last week and a half ( worse this week). Constant headaches without relief from advil , nausea ( more of a gagging feeling). Terrible fatigue , and when I lay down I get heart palpitations and a slight cough. Today I started with an upper back ache that also advil doesn t help. Any idea what is going on? Thank u in advance, Trina
